"Repent ye; for the kingdom of heaven is at hand." Matthew 3:3
Additional readings: Isaiah 1:1-20
In the childhood of the human race, before men had departed from right ways of life, heaven was near to them. They could be led directly by the Lord, for their hearts and minds were open to him. Of this Golden Age of the human race it is written, "Man walked with God." But we have all read in the history of the human race as revealed in the Scripture the account of how many departed from the way of life and, following the devices of his own heart, closed his mind to the direct reception of goodness and truth from the Lord, until finally he reached a state in which all true knowledge of God and heaven was lost.
Then the Lord came to bring salvation to mankind, and preparation for His reception was made through John the Baptist, the messenger sent in fulfillment of a prophecy given centuries before. John’s message is our text: "Repent ye, for the kingdom of heaven is at hand." And when John was put to death, and the Lord began His active ministry in the world, the words of our text were also His first message. For He came to make clear the way of life, and wrong ideas held possession of the minds of men then, as they do of many minds today.
It is not by chance that this first message turns our thoughts to heaven. The purpose of our creation is that we may so live that we shall find our homes in heaven. Belief in heaven had been lost, along with the knowledge about it. And today belief in heaven is for the most part vague, and many think that eternal life does not mean personal existence in the spiritual world, but only the persistence of one’s influence in this world. Great men like Homer, Plato, Moses, Shakespeare, Gladstone, Lincoln, Pasteur, and many others perpetuate themselves in the influence they exert in the minds of living men. This, they say, is what is meant by immortality, by everlasting life. But we should realize that this type of everlasting life is open to the evil as well as to the good. A Diocletian may be remembered forever as well as the beloved Apostle. We need to know the truth that men and women, as individuals, live forever after death in the spiritual world.
But this is not the implication of the text which I have chosen for consideration this morning." The kingdom of heaven is at hand." We know that heaven is not in some remote part of the natural sky, that we cannot say, "Lo, here, or Lo, there" (Luke 17:21). But we are still apt to think of it as far away. We are also inclined to think of it as remote in time. We speak commonly of the "future" world. In the thought of some even, it lies at the indefinitely remote time, when they expect a general resurrection along with others; death is the gateway of heaven, but heaven still seems too distant to be of much practical and present interest.
But the truth is that heaven is far away neither in space nor in time. It is here, it is now, it is "at hand." We live in it now, or we may do so. It is a present reality, the most real and the most important element of the life we are now living. When we speak of heaven, and of living for heaven, we are not, as some charge, setting our hearts on something far away, and despising the real world in which we now are. If one lives for a far-off heaven — and no doubt some have lived so — he may be careless of this world’s joys and sorrows, of opportunities for usefulness, keeping his eyes fixed on some vision of the future. But we may live for heaven and still live thoroughly in the present. We ought to value heaven as the most real of present realities. The Gospel is true: "The kingdom of heaven is at hand."
We are taught in the New Church that heaven is essentially a state of human feeling, thought and life, a state in which love to the Lord and love to the neighbor are the ruling motives. We are taught that no outward paradise which could be made by human or by Divine skill would be a heaven if those affections were absent from the heart, that there is no real or lasting satisfaction except in the exercise of these affections. It follows that we can come into heaven in this world, and live in heaven while we live on earth, for we may learn here to love the Lord and one another, and to find our chief enjoyment in the exercise of these heavenly loves.
But this is an abstract way of speaking. Concretely, heaven is not merely a heavenly state in ourselves; it is the great world of human beings who are living in that state, those people in whose hearts are heavenly affections, whose minds are bright with spiritual light, and whose hands are busy with heavenly works. There are many such people in this world. There are countless more who have gone from the earth to the spiritual world, and are there living the same good life under freer and happier conditions. All these people are heaven.
When we have love to the Lord and the neighbor in ourselves, we are brought spiritually near to those in like affections, both of this world and of the spiritual world. It is not a figure of speech when we say that heaven is about us when we are in heavenly states. It is a literal and positive fact. Heaven is so really around us at such times that if it were granted to us, as it was to Elisha’s servant and to others in Bible days to have our spiritual eyes opened, we should see the angels who are our companions and the beautiful land in which they dwell. Among them we should see and recognize some who were dear to us on earth, who still love and help us, and there would be some whom we had not known before but who would from the first glance seem to us as old friends, because they have similar desires and thoughts. And we should recognize them as the source of our happiness.
The Lord created the world and all things in it. All things in the world were made for man to use and enjoy, from the very materials of the earth to all the myriad things of the vegetable and animal kingdoms, the beast of the field, the fowl of the air, and the fish of the sea. For man’s needs of food, clothing, shelter, for gratification of his senses, and the improvement of his mind these things were made. All these were created and given to man for blessings. But they are subject to one important condition: man must indeed labor to make these things of service to himself, but he must also use them in the service of others. Only so can he have any security or peace. The world of nature and of human beings is not for one man, or a few men, or a nation to control or exploit. Indeed we cannot rightly claim sovereignty over ourselves. We need the guidance of the Lord. And whatever under the Divine Providence we have been able to acquire, whether of material wealth, or of skill, or of learning, we did not acquire it by our unaided efforts. Our daily knowledge of the happenings in the world, our libraries, our schools are made possible by the labor of mind and body of other men and women, great or humble, living or dead. We depend on others and they on us, and life and security today, as always, depend upon the honesty and good will of the community in which we live.
Yet we should also realize that behind the labors and sufferings and the honesty and good will of men stands the Lord. Through His power alone man achieves progress. It is a law of the Divine Providence that man must act in freedom according to reason. This applies to the life of nations as well as to the life of individuals. But the Lord is present and operative always.
For infinitely wise and good reasons, the Lord does not draw the veil aside for us and allow us to see the heavenly world. Some argue that if only they could see heaven, they would believe in it. But to see that world as an outward, objective reality would destroy our freedom. We should be lured by its outward attractiveness, and it would be less possible for us to come into its true spirit.
When we are living in selfish and evil affections, we are in hell. Not only is hell within us at such times but it is also about us, not by a figure of speech, but actually. We are breathing its poisoned atmosphere and, if our eyes were opened, we should see the forms and faces of those who find their life in evil and who exult in influencing others to evil. Why, at least then, does the Lord not draw the veil aside and show us the terribleness of evil? The sight might for the moment frighten us, but we should be less able to shun evil freely because it is evil, and our power to escape permanently from it would be greatly lessened.
If we are tempted to question the Lord’s Providence in not revealing to us more openly the conditions of the good and evil in the spiritual world, we do well to remember His words, "They have Moses and the prophets, let them hear them….If they hear not Moses and the prophets, neither will they be persuaded though one rose from the dead" (Luke 16:29-31).
The Lord said, "Seek ye first the kingdom of God and His righteousness" (Matthew 6:33). We should seek those good things which endure forever, and should not sacrifice them for the sake of money or health or life itself. To acquire love to the Lord and to the neighbor is the only thing worth living for. Our business dealings should have as their motive the love of use, of service to others. The most necessary thing in making a home is having in it the sunshine of heaven. The only absolute requirement for our happiness as we go to and fro in the ways of the world is that heaven shall go with us. This is to live for heaven, and yet to live must fully in the present. This is the practical meaning of living for heaven.
It may be stated still more simply. Heaven is not heaven from locality, neither is it heaven from anything which belongs to the angels as their own. It is heaven from what is received from the Lord into the lives and hearts of the angels. To be near the Lord, not in place merely, but in heart, to feel the protection and peace of His presence is heaven. Heaven is being near to the Lord and keeping near to Him. There is no other heaven for men or angels.
"The kingdom of heaven is at hand." When John first spoke this message, the kingdom of heaven was in a special sense at hand, because the Lord had come to live with men and to make Himself accessible to them. A power to heal and bless went forth from the Lord during His life on earth. Men obsessed felt his saving power and sat at His feet clothed and in their right mind.
At the Transfiguration Peter said, "Lord, it is good for us to be here" (Matthew 17:4, Mark 9:5, Luke 9:33). In following the Lord, in hearing His Word and in doing His work, they were tasting of heaven. But we need to note that the mere physical nearness of the Lord did not make heaven. Some cried out with fear at His approach. It was not heaven to them. It was not heaven to those who followed Him to accuse and to betray Him. His presence was a blessing only to those who in some measure drew near to Him in spirit.
Even in the Lord’s coming on earth the kingdom of heaven was not forced on me. It was made accessible to them; it was brought within their reach.
It is brought within our reach. Just as there is no royal road to knowledge, there is no royal road to heaven. We must cease to do evil before we can learn to do well. Repentance, the willingness to recognize and acknowledge our faults and weaknesses and to struggle to overcome them opens the door. Heavenly life comes into the soul when selfish desires are replaced by kindly thoughts and the desire to serve. The Lord tell us to seek these heavenly virtues now, not for the sake of honor for ourselves, but that we may be really kind and helpful to others, that our lives may have something of the Lord’s love in them. Then we shall find that life here makes one with heavenly life, and that our Heavenly Father is the Source of happiness in both alike.
109. To him that overcometh will I give to eat of the tree of life. That this signifies that he who receives in the heart shall be filled with the good of love, and hence with heavenly joy, is evident from the signification of overcoming, as being to receive in the heart, concerning which we shall treat in what follows; and from the signification of eating, as being to appropriate and to be conjoined (concerning which see Arcana Coelestia, n. 2187, 2343, 3168, 3813, 5643); and from the signification of the tree of life, as being the good of love, and thence heavenly joy, concerning which also we shall speak presently. The reason why to overcome denotes to receive in the heart is, that everyone who is about to receive spiritual life will fight against the evils and falsities of his natural life, and when he overcomes them, then goods and truths, which belong to the spiritual life, are received in the heart (to receive in the heart is to receive in the will and love, for the heart in the Word signifies the will and love, as may be seen, Arcana Coelestia, n. 2930, 3313, 7542, 8910, 9050, 9113, 10,336); wherefore to receive goods and truths in the heart, is to do them from the will or love; this is what is meant by overcoming.
 The reason why the tree of life signifies the good of love, and thence heavenly joy is, that trees signify those things that are internally in man, which pertain to his interior mind (mens), or his external mind (animus), the boughs and leaves those things which pertain to the knowledges (cognitiones) of truth and good, and the fruits the goods of life themselves. This signification of trees originates in the spiritual world; for in that world trees of all kinds are seen; and these trees correspond to the interiors of the minds of angels and spirits; beautiful and fruitful trees to the interiors of those who are in the good of love, and thence in wisdom; trees less beautiful and fruitful to those who are in the good of faith; but trees bearing leaves only, and without fruit, to those who are only in the knowledges (cognitiones) of truth; and trees of a dismal hue, with malignant fruits, to those who are in knowledges (cognitiones) and in evil of life; but by those who are not in knowledges, and are in evil of life, trees are not seen, but instead stones and sand.
These appearances in the spiritual world, actually flow from correspondence; for the interiors of the mind of the inhabitants of that world are by such forms actually presented before their eyes. (These things may be seen better from two articles in the work, Heaven and Hell; in the first, where the correspondence of heaven with all things of the earth is treated of, n. 103-115; and in the other, where representatives and appearances in heaven are treated of, n. 170-176, and n. 177-190.)
 This then is why trees are so often mentioned in the Word, by which are signified those things which pertain to a man's mind; and why it is, that in the first chapters of Genesis, two trees are said to have been placed in the garden of Eden, one of which was called the tree of life, and the other the tree of knowledge (scientia). By the tree of life mentioned there is signified the good of love to the Lord, and thence heavenly joy, which those possessed who at that time formed the church, and who are meant by the man and his wife; and by the tree of knowledge is signified the delight of knowledges (cognitiones) without any other use than to be accounted learned, and to acquire renown for erudition, solely for the sake of honour or gain. The reason why the tree of life also signifies heavenly joy is, because the good of love to the Lord, which is specifically signified by that tree, has heavenly joy in it. (See the work, Heaven and Hell, n. 395-414, and The Doctrine of the New Jerusalem, n. 230-239.)
 That trees, so often mentioned in the Word, signify the interiors of man's internal and external minds, and the things produced by the trees, as the leaves and fruit, such things as are derived from them, is evident from the following passages:
"I will give in the desert the cedar, the schittah tree, and the myrtle, and the oil tree; I will set in the wilderness the fir tree, the pine and the box" (Isa. xli. 19).
The establishment of the church is there treated of;
"The glory of Lebanon shall come unto thee, the fir tree, the pine tree, and the box together, to beautify the place of my sanctuary" (Isa. lx. 13).
"Let all the trees of the field know that I, Jehovah, humble the lofty tree, and exalt the humble tree, cause the green tree to become dry, and make the dry tree to bud" (Ezek. xvii. 24).
"Behold, I will kindle a fire in thee, and it shall consume every green tree in thee, and every dry tree" (Ezek. xx. 47).
"The vine is dried up, and the fig tree languisheth; the pomegranate tree, the palm tree also, and the apple tree, all the trees of the field are withered, because joy is withered away from the sons of men" (Joel i. 12).
"When the angel sounded, there followed hail and fire which fell upon the earth; and the third part of the trees was burnt up" (Apoc. viii. 7)
Nebuchadnezzar saw in a dream "a tree in the midst of the earth, and the height thereof was great, the leaf thereof fair, and the flower thereof much, and in it was food for all" (Dan. iv. 10-12).
Because trees in general signify such things as pertain to man, and constitute the interiors of his mind, and thus the spiritual things pertaining to the church, and both the latter and the former are various, therefore so many species of trees are mentioned, and every species signifies something different. (What the various species signify is shown in Arcana Coelestia, as what is signified by the oil tree, n. 9277, 10,261 what by the cedar, n. 9472, 9486, 9528, 9715, 10,178 what by the vine, n. 1069, 5113, 6375, 6378, 9277; what by the fig, n. 217, 4231, 5113, and so forth.)
(References: Arcana Coelestia 217, Arcana Coelestia 1069, Arcana Coelestia 4231, Arcana Coelestia 5113, Arcana Coelestia 6375, 6378, Arcana Coelestia 9277, Arcana Coelestia 9472, 9486, 9528, 9715, 10178, 10261; Daniel 4:10-12; Ezekiel 17:24, 20:47; Isaiah 41:19, 60:13; Joel 1:12; Revelation 8:7)
 Moreover, the things which are upon trees, as leaves and fruits, signify those things that pertain to man; leaves signify the truths pertaining to him, and fruits the goods, as in the following passages:
"He shall be as a tree planted by the waters, and that spreadeth out her roots by the river; her leaf shall be green; neither shall it cease from yielding fruit" (Jer. xvii. 8).
By the river which went out from the house of God "upon the bank thereof, on this side and on that side, ascendeth the tree of food, whose leaf falleth not off, nor is its fruit consumed; it springeth again in its months, because its waters issue out of the sanctuary, whence its fruit is for food, and its leaf for medicine" (Ezek. xlvii. 12).
"In the midst of the street of it, and of the river (going out from the throne of God and the Lamb), on this side and on that side, was there the tree of life bearing twelve fruits, and yielding her fruit every month, and the leaves of the tree are for the healing of the nations" (Apoc. xxii. 1, 2).
"Blessed is the man whose delight is in the law; he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season, his leaf also shall not wither" (Ps. i. 1-3).
"Be not afraid, for the tree shall bear her fruit, the fig tree and the vine shall yield their strength" (Joel ii. 22).
"The trees of Jehovah are full of sap, the cedars of Lebanon which he hath planted" (Ps. civ. 16).
"Praise Jehovah, ye fruitful trees, and all cedars" (Ps. cxlviii. 9).
 Because fruits signified the goods of life with man, therefore in the Israelitish church, which was a representative church, it was commanded that the fruit of trees, like the men themselves, should be circumcised, concerning which it is thus written: The fruit of a tree serving for food shall be uncircumcised in the land of Canaan;
"three years shall it be uncircumcised unto you; and in the fourth year all the fruit thereof shall be holy, the praises of Jehovah. And in the fifth year shall ye eat of the fruit thereof" (Lev. xix. 23, 24, 25).
Because the fruit of the tree signified goods of life, therefore also it was commanded, that
in the feast of tabernacles they should take the fruit of the tree of honour, and the boughs, and should rejoice before Jehovah, and thus they should keep the feast (Lev. xxiii. 40, 41);
for by tabernacles were signified the goods of celestial love, and thence holy worship (see Arcana Coelestia, n. 414, 1102, 2145, 2152, 3312, 4391, 10,545); and by the feast of tabernacles was signified the implantation of that good of love (n. 9296). Because fruit signified the goods of love, which are the goods of life, therefore it was among the blessings that the tree of the field should yield its fruit; and among the curses that it should not yield its fruit (Lev. xxvi. 4, 20). And therefore also they were forbidden, when any city was besieged, to lay the axe to any tree of good fruit (Deut. xx. 19, 20).
From these considerations it is now evident that by fruits are signified the goods of love, or, what is the same, goods of life, which are also called works, as also what is meant in these passages in the Evangelists:
"The axe lies at the root of the trees; every tree which bringeth not forth good fruit shall be hewn down and cast into the fire" (Matt. iii. 10; vii. 16-21).
Either make the tree good and the fruit good, or else make the tree corrupt and the fruit corrupt; for the tree is known by its fruit" (Matt. xii. 33; Luke vi. 43, 44).
"Every branch in me that beareth not fruit shall be taken away: but every branch that beareth fruit shall be purged, that it may bring forth more fruit" (John xv. 2-8).
"A certain man had a fig-tree planted in his vineyard he came seeking fruit thereon, and found none. Then saith he unto the vinedresser, Behold, these three years I come seeking fruit on the fig-tree, and find none: cut it down; why cumbereth it the ground?" (Luke xiii. 6-9).
"Jesus saw a fig-tree in the way; he came to it, and found nothing thereon but leaves only; he said, Let no fruit grow on thee for ever. And immediately the fig tree withered away" (Matt. xxi. 19; Mark xi. 1:13, 14, 20).
By the fig-tree is signified the natural man and his interiors, and by the fruit his goods (see Arcana Coelestia, n. 217, 4231, 5113); but leaves signify knowledges (cognitiones), (n. 885). Hence it is clear what is signified by the fig-tree withering away, because the Lord found on it leaves only, and no fruit. All these passages are quoted in order that it may be known that by the tree of life in the midst of the paradise of God, is signified the good of love proceeding from the Lord, and heavenly joy therefrom.
