275. Verse 6. And in sight of the throne a glassy sea like crystal, signifies the appearance of [Divine] truth in ultimates where its generals are, and its pellucidity by virtue of the influx of Divine truth united to Divine good in firsts. This is evident from the signification of "in sight of the throne," as being appearance; also from the signification of "glassy," as being pellucid. It is also said "like crystal," that pellucidity from the influx of Divine truth united to Divine good in firsts may be described; this is signified by "the seven lamps of fire burning before the throne" (as shown just above, n. 274. In this and what precedes, the state of the whole heaven arranged in order for judgment is described, and its ultimate is meant by "the glassy sea like crystal." The truth of the ultimate heaven is signified by "a glassy sea" because "sea" signifies the generals of truth, such truth as exists in the ultimates of heaven, and with man in the natural man, which truth is called knowledge [scientificum]. The "sea" signifies such truths because in the sea is the gathering together of waters, and "waters" signify truths (See above, n. 71).

[2] That this is the signification of "sea" is evident from many passages in the Word, a number of which I will cite here. In Isaiah:

I will shut up the Egyptians into the land of a hard lord; and a fierce king shall rule over them. Then the waters shall fail from the sea, and the river shall dry up and become dry (Isaiah 19:4, 6).

By "the Egyptians" knowledges [scientiae] that are of the natural man are meant; "the hard lord into whose hands they should be shut up" signifies the evil of self-love; "a fierce king" signifies falsity therefrom; "the waters shall fail from the sea" signifies that with all the abundance of knowledges [scientiarum] there still are no truths; and "the river shall dry up and become dry" signifies that there is no doctrine of truth and no intelligence therefrom.

[3] In the same:

Jehovah will visit with His sword, hard, great, and strong, upon leviathan the stretched out serpent, and leviathan the crooked serpent, and will slay the whales that are in the sea (Isaiah 27:1).

This is also said of "Egypt," by which knowledges [scientiae] that are of the natural man are signified; "leviathan the stretched out serpent" signifies those who reject all things which they do not see with the eyes, thus the merely sensual, who are without faith, because they do not comprehend. "Leviathan the crooked serpent" signifies those who, for the same reason, do not believe, and yet say that they believe. "The sword, hard, and great, and strong, with which they shall be visited," signifies the extinction of all truth, for "sword" signifies falsity destroying truth. "The whales in the sea," that shall be slain, signify knowledges [scientifica] in general. (That these are signified by "whales," see Arcana Coelestia 7293.)

[4] In the same:

Let the inhabitants of the isle be still; thou merchant of Zidon passing over the sea, they have filled thee. Blush, O Zidon, for the sea hath said, the stronghold of the sea, saying, I have not travailed, and I have not brought forth, and I have not brought up young men, and have not raised up virgins; when the report comes to Egypt they shall be seized with grief, as by the report respecting Tyre (Isaiah 23:2-5).

"Zidon" and "Tyre" signify the knowledges of good and truth; therefore it is said "the merchant of Zidon passing over the sea," "merchant" meaning one who acquires these knowledges for himself and communicates them. That they acquired for themselves thereby nothing of good and truth is signified by "the sea said, I have not travailed and I have not brought forth, I have not brought up young men, and have not raised up virgins;" "to travail and bring forth" is to produce something from knowledges; "young men" mean truths, and "virgins" goods. That the use of cognitions and knowledges (cognitionum et scientiarum) would therefore perish, is signified by "when the report comes to Egypt they shall be seized with grief, as by the report respecting Tyre."

[5] In Ezekiel:

All the princes of the sea shall come down from their thrones, and cast away their robes, and strip off their broidered garments, they shall be clothed with terrors. They shall take up a lamentation over thee, and shall say, How hast thou perished, thou that dwelt by the seas, the renowned city which was strong in the sea; therefore the islands in the sea shall be dismayed at thy outcome (Ezekiel 26:15-18).

These things are said of "Tyre," which signifies the cognitions of truth, the neglect and loss of which are thus described; the "princes of the sea that shall come down from their thrones" signify primary cognitions; that these together with knowledges [scientificis] shall be abandoned is signified by "they shall cast away their robes, and strip off their broidered garments;" "broidered work," is knowledges [scientificum]; "the city that dwelt by the seas and was strong in the sea" signifies the power of knowing in all abundance ("seas" signify collections); "the islands in the sea" signify nations more remote from truths that long for cognitions, of which it is said "therefore the islands in the sea shall be dismayed at thy outcome."

[6] In Isaiah:

They shall not do evil nor corrupt themselves in all the mountain of My holiness; for the earth shall be full of the knowledge [scientifia] of Jehovah, as the waters cover the sea (Isaiah 11:9).

This treats of a new heaven and a new church, which are meant by "mountain of holiness," in which "they shall not do evil nor corrupt themselves;" their understanding of truth from the Lord is described by "the earth shall be full of the knowledge [scientia] of Jehovah; "and as waters" signify truths, and the "sea" the fullness of them, it is said, "as the waters cover the sea."

[7] In the same:

By My rebuke I dry up the sea, I make the rivers a wilderness; their fish shall become putrid because there is no water, and shall die of thirst (Isaiah 50:2).

"To dry up the sea" signifies an entire lack of the general knowledges of truth; "to make the rivers a wilderness" signifies the deprivation of all truth and of intelligence therefrom; "the fish shall become putrid" signifies that the knowledges [scientifica] pertaining to the natural man shall be without any spiritual life; this takes place when they are applied to confirm falsities in opposition to the truths of the church; "by cause there is no water" signifies because there is no truth; "to die of thirst" signifies the extinction of truth. (That "rivers" signify the things of intelligence, see Arcana Coelestia 108, 2702[1-17], Arcana Coelestia 2702[1-17], 3051; that "wilderness" signifies where there is no good because there is no truth, n. 2708, 4736, 7055; that "fish" signifies the knowledge [scientificum] pertaining to the natural man, n. 40, 991; that "water" signifies truth, n. 2702, 3058, 3424, 5668, 8568; and that "to die of thirst" signifies the absence of spiritual life from lack of truth, n. Arcana Coelestia 8568[1-10].

[8] In David:

O Jehovah, Thou rulest in the uprising of the sea; when it raiseth up its waves (Psalms 89:9).

The "sea" here signifies the natural man, because in the natural man are the generals of truth; "the uprising of the sea" signifies its exalting itself against the Divine, denying the things that are of the church; the "waves" which it raiseth up signify falsities.

[9] In the same:

Jehovah hath founded the world upon the seas, and established it upon the rivers (Psalms 24:2).

The "world" signifies the church; the "seas" knowledges in general which are in the natural man; and "rivers" the truths of faith; upon these two the church has its foundation.

[10] In Amos:

Jehovah, who buildeth His steps in the heavens, and calleth the waters of the sea, and poureth them out upon the faces of the earth (Amos 9:6).

"The steps that Jehovah buildeth in the heavens" signify interior truths which are called spiritual; "the waters of the sea" signify exterior truths, which are natural because they are in the natural man; "to pour them out upon the faces of the earth" signifies upon the men of the church, for the "earth" is the church.

[11] In David:

By the word of Jehovah were the heavens made; and all the hosts of them by the breath of His mouth. He gathereth the waters of the sea together as an heap; He giveth the deeps in treasuries (Psalms 33:6-7).

"The word of Jehovah by which the heavens were made," and "the breath of His mouth by which all the hosts of them were made," signify Divine truth proceeding from the Lord; "the hosts of the heavens" are all things of love and faith; "the waters of the sea that He gathereth together as an heap" signify the knowledges of truth, and truths in general, which are together in the natural man; "the deeps that He gives in treasuries" signify sensual knowledges [scientifica sensualia], which are the most general and ultimate things of the natural man, and in which at the same time are interior or higher truths, therefore they are called "treasures."

[12] In the same:

Jehovah hath founded the earth upon its bases, that it be not removed for ever and ever. Thou hast covered it with the deep as with a vesture (Psalms 104:5-6).

The "earth" signifies the church; "the bases on which Jehovah hath founded it for ever" are the knowledges of truth and good; "the deep with which He hath covered it as with a vesture" signifies sensual knowledge [scientificum sensuale], which is the ultimate of the natural man, and being the ultimate, it is said that "He covered it as with a vesture."

[13] In the same:

Jehovah, Thy way is in the sea, and Thy path in many waters, yet Thy footsteps have not been known (Psalms 77:19).

In Isaiah:

Thus saith Jehovah, I who have given a way in the sea, and a path in the mighty waters (Isaiah 43:16).

That "sea" here does not mean the sea, nor "waters" the waters, is clear, since it is said that therein "are the way and the path of Jehovah;" therefore by "sea" and by "waters" are meant such things as Jehovah or the Lord is in, which are the knowledges of truth in general from the Word, and the truths therein; "the sea" being such knowledges, and "waters" truths. Knowledges and truths differ in this, that knowledges are of the natural man, and truths of the spiritual man.

[14] In Jeremiah:

Behold, I will plead thy cause, and will revenge thy revenging; that I may dry up the sea of Babylon, and make dry her fountain. The sea shall come up upon Babylon, she shall be covered with the multitude of its waves (Jeremiah 51:36, 42).

By "Babylon" those who profane goods are meant; "the sea of Babylon" means their traditions, which are the adulterations of good from the Word; "the waves" are the falsities from these; their destruction at the Last Judgment is hereby described.

[15] In the same:

A people coming from the north, and a great nation and many kings shall be stirred up from the sides of the earth. Their voice maketh a tumult like the sea, and they ride upon horses (Jeremiah 50:41, 42).

"A people coming from the north" are those who are in falsities from evil; "the great nation" means evils; and "many kings" falsities; "the sides of the earth" are the things outside of the church, and those that are not of the church, for the "earth" means the church; "their voice maketh a tumult like the sea" means falsity from the natural man exalting itself against the truth of the church; "the horses upon which they ride" are reasonings from the fallacies of the senses.

[16] In the same:

Jehovah giveth the sun for light by day, the statutes of the moon and stars for light by night, stirring up the sea so that the waves thereof roar (Jeremiah 31:35).

"The sun from which is the light of day" signifies the good of celestial love, from which is the perception of truth; "the statutes of the moon and stars, from which is the light of night," signify truths from spiritual good and from knowledges, by which there is intelligence; "the sea that is stirred up, and the waves that roar," signify the generals of truth in the natural man, and knowledges [scientifica].

[17] In Isaiah:

The wicked are like the troubled sea when it cannot be quiet, but its waters cast up filth and mire (Isaiah 57:20).

"The troubled sea which is like the wicked," signifies reasonings from falsities; "the waters that cast up filth and mire," signify the falsities themselves, from which come evils of life and falsities of doctrine.

[18] In Ezekiel:

I will stretch out Mine hand upon the Philistines, and I will cut off the Cherethites, and destroy the remnant of the sea coast (Ezekiel 25:16).

"The Philistines" signify those who are in the doctrine of faith alone, and "the remnant of the sea coast that shall be destroyed," signifies all things of truth.

[19] In Hosea:

I will not return to destroy Ephraim. They shall go after Jehovah; and the sons from the sea shall draw near with honor, with honor shall they come as a bird out of Egypt, and as a dove out of the land of Assyria (Hosea 11:9-11).

"Ephraim" signifies the church in respect to the understanding of truth; "the sons from the sea, who shall draw near," signify truths from a common fountain, which is the Word; "a bird out of Egypt" signifies knowledge [scientificum] agreeing; and "a dove out of the land of Assyria" signifies the rational.

[20] In Zechariah:

In that day living waters shall go out from Jerusalem; part of them to the eastern sea, and part of them to the hinder sea (Zechariah 14:8).

"Living waters from Jerusalem" signify truths from a spiritual origin in the church, which are the truths that are received by man when he is illustrated by the Lord while he is reading the Word. "Jerusalem" is the church in respect to doctrine, the "sea" signifies the natural man, into which those things that are in the spiritual man descend; the "eastern sea" signifies the natural man in respect to good; and the "hinder sea" the natural man in respect to truth; and as the natural man is in the generals of truth, "sea" also signifies the general of truth.

[21] He who knows nothing about the spiritual man, and the truths and goods that are therein, may suppose that the truths that are in the natural man, and are called cognitions and knowledges [scientifica] are not merely the generals of truth, but are all there is of truth with man. But let him know that the truths in the spiritual man, from which those are that are in the natural, are incomparably more numerous; but these truths in the spiritual man do not come to the perception of the natural man until he enters the spiritual world, which is after death; for then man puts off the natural and puts on the spiritual. That this is so can be seen from this fact alone, that angels are in intelligence and wisdom ineffable as compared with man, and yet they are from the human race. (That angels are from the human race, see in the small work onThe Last Judgment 14-22 and 23-27)

[22] As the "sea" signifies the generals of truth, therefore the great vessel, which was for general washing, was called "the brazen sea" (1 Kings 7:23-26); for the "washings" represented purifications from falsities and evils, and "waters" signify truths, by which purifications are effected; and as all truths are from good, the containing vessel was made of brass, and was therefore called "the barren sea," for brass signifies good. Spiritual purification, which is called purification from falsities and evils, is there fully described by the measurements of that vessel, and by the bases thereof, understood in a spiritual sense. From what has been brought forward it can be seen that "sea" signifies the generals of truth or the knowledges of truth together and collectively. But what further is signified by "sea" will be shown in the explanation of what follows, for "sea" is used in various senses (as in Revelation 5:13; 7:1-3; 8:8, 9; 10:2, 8; 12:12; 13:1; 14:7; 15:2; 16:3; 18:17, 19, 21; 20:13; 21:1).

342. Verse 13. And every created thing that is in heaven, and on the earth, and under the earth, and those that are in the sea, and all that are in them, heard I saying, signifies the acknowledgment and consequent glorification of the Lord by the angels that are in the lowest parts of heaven. This is evident from the signification of "every created thing" as being all who are reformed. That "to be created" signifies to be reformed and regenerated, see above (n. 294); therefore "created thing" signifies what is reformed and regenerated; but in reference to the angels, of whom these things are said, it signifies those who were reformed in the world, that is, created anew, for all such are in heaven. "Created thing" here has a like meaning as "creature" in Mark:

Jesus said to the disciples, Go into all the world, preach ye the gospel to every creature (Mark 16:15);

where "every creature" means all who receive the gospel and can be reformed by it; the rest are not meant by "creatures," because they do not receive, but hear and reject.

[2] From this the nature of the Word in the sense of the letter can be seen, namely, why the term "creature" is used, and why it is said "every created thing that is in heaven, and on the earth, and under the earth, and those that are in the sea, and all that are in them." He who does not know that the sense of the letter is made up of such things as appear before the eyes, and that these signify spiritual things, may easily be led to believe that "every created thing that is in heaven, and on the earth, and under the earth, and those that are in the sea, and all that are in them," mean the birds that fly in the sky, the beasts that walk on the earth, and the fishes that are in the sea; and the more because in various other passages in the Word, like things are said of "the birds of heaven," the "beasts of the earth," and also of "whales" and "fishes" (as in Ezekiel 39:17; Psalms 148:7; Job 12:7, 8; Revelation 19:17). Still those whose minds can be somewhat elevated above the sense of the letter instantly perceive by interior sight that these things mean the angels and spirits who are in heaven and under heaven, and that it was these whom John heard when he was in the spirit; for it is said, "heard I saying, Unto Him that sitteth upon the throne, and unto the Lamb, be the blessing, and the honor, and the glory, and the might, unto the ages of the ages;" from which it can be seen that "every created thing" therein means the angels that are in the lowest parts of heaven; moreover, this follows from the fact that the preceding verses treat of the angels of the higher heavens and of the angels of the lower heavens, that they acknowledged and glorified the Lord (See above, n. 322, 335).

[3] It shall now be explained who are meant by those "in heaven," who by those "on the earth and under the earth," and who by those "in the sea." All these mean those who are in the ultimates of heaven, those "in heaven" meaning the higher there, those "on the earth and under the earth" the lower there, and those "in the sea" the lowest there. There are three heavens, and each heaven is divided into three degrees; the same is true of the angels who are in them; consequently in each heaven there are higher, middle, and lower angels; these three degrees of the lowest heaven are meant by those "in heaven," those "on the earth," and those "in the sea." (Respecting this division of the heavens and of each heaven, see Arcana Coelestia, n. 4938, 4939, 9992, 10005, 10017, 10068; and respecting the lowest degree, n. 3293, 3294, 3793, 4570, 5118, 5126, 5497, 5649, 9216; and in the work on Heaven and Hell 29-40.)

It should be known, that in the spiritual world, where spirits and angels are, all things have the same appearance as in the natural world where men are, namely, there are mountains, hills, lands, and seas (See above, n. 304). The angels who are in the third or inmost heaven dwell upon the mountains, those who are in the second or middle heaven dwell upon the hills, and those who are in the first or lowest heaven dwell upon the earth and under the earth, and in the seas. But the seas in which the lowest of that heaven dwell are not like the seas in which the evil dwell; their waters are different. The waters of the seas in which the well-disposed in the lowest heaven dwell are rare and pure; but the waters of the seas in which the evil dwell are gross and impure; thus they are entirely different seas.

[4] These seas I have several times been permitted to see, and also to converse with those who are in them; and it was found that those were there who had been in the world merely sensual, and yet well-disposed; and because they were sensual they were unable to understand what the spiritual is, but only what the natural is; nor could they apprehend the Word and the doctrine of the church from the Word except sensually. All these appear to be as if in a sea; but those who are in it do not seem to themselves to be in a sea, but as it were in an atmosphere like that in which they had lived while in the world; they appear to be in a sea only to those who are above them. At this day there is an immense number there, because so many at this day are sensual. This lowest part of heaven corresponds to the soles of the feet. This is the reason why seas are so often mentioned in the Word, and also fishes therein, "seas" there signifying the generals of truth which belong to the natural man, and "fishes" the sensual knowledges [scientifica sensualia], which are the lowest things of the natural man, consequently such persons, that is, those who are in these knowledges, are signified. (What sensual things and what sensual men are, and that they may be either good or evil, see in The Doctrine of the New Jerusalem 50 .) From this it can be known what is meant by "every created thing that is in the heaven, and on the earth, and under the earth, and those that are in the sea, and all that are in them."

[5] Like things are signified in the following passages by "seas," and by the things that are in them, which are called "fishes" and "whales." In David:

Let heaven and earth praise Jehovah, the seas, and every thing that creepeth therein. For God will save Zion, and will build the cities of Judah (Psalms 69:34-35).

It is said also "every thing that creepeth therein," meaning those who are sensual. "Zion, which God will save," and "the cities of Judah, which He will build," mean the celestial church and its doctrine, "Zion" that church, and "cities" the doctrine. There is a like meaning in these words in David:

Praise Jehovah from the earth, ye whales and all deeps (Psalms 148:7); "whales" meaning the same. For this reason Egypt also is called a "whale" (Ezekiel 29:3);

for "Egypt" signifies the knowing faculty in the natural man, and "whale" knowing in general.

[6] These things have a like signification also elsewhere in the same:

Thou madest him to rule over the works of Thy hands; Thou hast put all things under his feet; the flock and all herds, and also the beasts of the field, the bird of heaven, and the fishes of the sea (Psalms 8:6-8).

This treats of the Lord, and His Divine power over heaven and earth; and "the flocks and the herds, the beasts of the field, the bird of heaven, and the fishes of the sea," mean the men, spirits, and angels, in respect to spiritual and natural things pertaining to them; and the "fishes of the sea" meaning those who are in the ultimates of heaven (as above).

In Job:

Ask, I pray, the beasts, and they shall teach thee, or the birds of heaven, and they shall tell thee, or the shrub of the earth, and it shall teach thee; and the fishes of the sea shall declare unto thee. Who knoweth not from all these that the hand of Jehovah doeth this? (Job 12:7-10).

[7] In Ezekiel:

The angel brought me back unto the entrance of the house; where behold, waters went out from under the threshold of the house towards the east. Then he said unto me, These waters go out toward the eastern border, and go down into the plain, and come towards the sea; they are sent forth into the sea that the waters may be healed; whence it cometh to pass that every living soul that creepeth, whithersoever the brooks come, shall live; whence it is that there are exceeding many fish, because these waters come thither, and they are healed, that everything may live whither the brook cometh. According to their kind shall the fish be, as the fish of the great sea, exceeding many. The miry places thereof and the marshes thereof are not healed; they are given to the salt (Ezekiel 47:1, 8-11).

"The waters going out from under the threshold of the house towards the east" signify truths from a celestial origin, "waters" meaning truths, "the east" the good of heavenly love, and "house" heaven and the church; the "plain into which the waters go down," and "the sea into which they come," signify the ultimates of heaven and the church, consequently those who are in ultimates (of whom above), namely, those who are only in the knowledges of truth from the outmost sense of the Word, and apprehend those knowledges naturally and sensually. When such are in simple good, they receive the influx of the higher heavens, whence it is that they also receive in their knowledges what is spiritual, and thus some spiritual life. This is meant by "the waters are sent forth into the sea, that the waters may be healed; whence it cometh to pass that every living soul that creepeth, whithersoever the brooks come, shall live;" likewise by these words, "whence it cometh that there are exceeding many fish, because these waters come thither, and they are healed." But those who are such, and are not good, are meant by these words, "The miry places thereof and the marshes thereof are not healed; they are given to salt;" "to be given to salt" signifying not to receive spiritual life, but to remain in a life merely natural, which, separate from spiritual life, is defiled by falsities and evils, which are "miry places" and "marshes."

[8] Like things are signified by "sea," and by "fishes of the sea," in Isaiah:

Behold, at My rebuke I dry up the sea, I make the rivers into a wilderness; their fish stinketh because there is no water, and dieth of thirst (Isaiah 50:2).

"Rebuke" signifies the desolation of all truth; "sea" signifies where truth is in its outmost; "water" signifies truth from a spiritual origin; "to die for thirst" signifies desolation from lack of that truth; "fishes of the sea" signify those who are in the ultimates of truth, in whom there is no life from a spiritual origin.

[9] "Fishes of the sea" have a like signification in Ezekiel:

In My zeal, in the fire of My fury I will speak; that the fishes of the sea, and the fowl of the heavens, and the wild beast of the field, and every creeping thing that creepeth upon the ground may quake before Me (Ezekiel 38:19-20).

In Hosea:

They commit robbery, and bloods touch bloods; therefore the land shall mourn, and everyone that dwelleth therein shall languish; as to the wild beast of the field, and as to the fowl of the heavens, and also the fishes of the sea shall be gathered together (Hosea 4:2-3).

And in Zephaniah:

In taking away I will take away all things from upon the faces of the ground; I will take away man and beast; I will take away the fowl of the heavens, and the fishes of the sea (Zephaniah 1:2-3).

"Man and beast" when mentioned together signify the interior and exterior affections of good (See Arcana Coelestia 7424, 7523, 7872); and "the fowl of the heavens and the fishes of the sea" signify the affections of truth and the thoughts spiritual and natural, but in the passages here cited, that these are about to perish.

[10] This significance of "sea" and "fishes" comes from the appearance in the spiritual world; all societies there appear surrounded by an atmosphere corresponding to their affections and thoughts; those in the third heaven appear in an atmosphere pure as the ethereal atmosphere; those in the second heaven appear in an atmosphere less pure, like the aerial; while the societies in the lowest part of heaven appear surrounded by an atmosphere, as it were watery; but those in the hells appear surrounded by gross and impure atmospheres, some of them as if in black waters, and others in other ways. It is the affections and the thoughts therefrom that produce these appearances around them; for spheres are exhaled from all, and these spheres are changed into such appearances. (Of these spheres, see Arcana Coelestia 2489, 4464, 5179, 7454, 8630.) It is also from the appearance in the spiritual world that those who are in spiritual affection and in thought therefrom are signified by "the birds of heaven," and those who are in natural affection and in thought therefrom by "fishes;" for both birds and fishes appear there, birds over the lands, and fishes in the seas. The affections and consequent thoughts of those who are there are what so appear; this is known to all who are in that world; and both the birds and the fishes have been many times seen by me: this appearance is from correspondence. From this it can be seen why "seas" signify the generals of truth, and "whales" and "fishes" the affections and thoughts of those who are in the generals of truth. That "seas" signify the generals of truth has been shown above n. 275.

[11] The quality of those in the spiritual world who dwell in that watery atmosphere which is meant by "seas," I will illustrate by a single example. When such read these words in David:

Everything that Jehovah willeth He doeth, in heaven and on earth, in the seas and all deeps (Psalms 135:6);

they do not know otherwise than that "heaven" means the heaven that is visible before our eyes, and "earth" the habitable earth, and "seas" and "deeps" the seas and deeps, thus that Jehovah does in these whatsoever He wills; and they cannot be led to believe that "heaven" means the angelic heaven; "earth" those there who are below, and "seas" and "depths" those there who are in the lowest parts. Because these things are spiritual, and above the sense of the letter, they are not willing and are scarcely able to perceive them because they see all things naturally and sensually.

[12] For this reason, from these words in Revelation:

I saw a new heaven and a new earth; for the first heaven and the first earth were passed away (Revelation 21:1).

It has been understood heretofore that the visible heaven and the habitable earth were to perish, and that a new heaven and a new earth were to arise. That "heaven" here means the heaven where angels are, and "earth" means the church where men are, and that these are to become new, those who think merely naturally and sensually are not willing to admit, and therefore do not understand; for they do not suffer their mind to be elevated out of the natural light into spiritual light. With such this is difficult, so much so that they can hardly bear that the Word should have any meaning beyond what the letter in its own sense declares and the natural man apprehends. Such persons are not unlike those birds that see and sing in dark places, but in the light of day blink with their eyes and see but little. The good among such are like these birds, and also like flying fishes; but the evil of this class are like night owls and horned owls, which altogether shun the light of day, or like fishes that cannot be elevated into the air without loss of life. The reason is that with the good of this class the internal spiritual man receives some little spiritual influx from heaven, consequently some perception that a thing is so although they do not see it; while with the evil of this class the internal spiritual man is entirely closed up. For everyone has an internal and an external man, or a spiritual and a natural; the internal or spiritual man sees from the light of heaven, but the external or natural man sees from the light of the world.
