2. Before treating of the New Jerusalem and its doctrine, something shall be said of the New Heaven and the New Earth. In the small work on The Last Judgment and the Destruction of Babylon it was shown what is meant by the "first heaven and the first earth" which had passed away. After they had passed away, and thus after the Last Judgment had been accomplished, the new heaven was created, that is, formed by the Lord. This heaven was formed of all those who after the Lord's advent even to the present time, had lived a life of faith and charity; since they alone were forms of heaven. For the form of heaven, according to which all consociations and communications are there effected, is the form of Divine Truth from the Divine Good which proceeds from the Lord; and this form a man puts on as to his spirit by a life according to Divine Truth.

That the form of heaven is from this source, may be seen in the work Heaven and Hell 200-212; and that all angels are forms of heaven, in Heaven and Hell 51-58, 73-77. From this it may be known, of whom the new heaven was composed, and hence also what its quality is; namely, that it is altogether of one mind; for he, who lives a life of faith and charity, loves another as himself, and through love conjoins him to himself, and thus reciprocally and mutually, because love in the spiritual world is conjunction. When, therefore, all act alike, then from many, yea, from countless numbers consociated according to the form of heaven, there arises one mind, and there results, as it were, a one; for there is nothing which separates and divides, but everything conjoins and unites.

9603. One measure for all the curtains. That this signifies a like state of the matter, is evident from the signification of a “measure,” as being the state of a thing as to truth (see n. 3104); consequently “one measure for all the curtains” denotes a like state of the matter for all the truths. By a like state of the matter, when said concerning the truths of faith in the spiritual kingdom, is meant that they all look to good, and that through good they look to the Lord from whom they are; for the truths which do not look to good, and thus to the Lord, are not truths of faith, consequently are not the truths of the church or of heaven. The truths which look in another direction may indeed in their external form appear like truths, but they are not truths, because they are devoid of life; for the life of truth is good, and good is from the Lord, who alone is life. Truths which look in another direction are like the members of a body without a soul, which are not members of any body, because they are lifeless, and therefore of no use.

[2] That “measure” signifies the state of a thing as to truth, and also the state of a thing as to good, is evident from the passages in the Word that treat of the measurements of the New Jerusalem, and also of the new temple. By the “New” or “Holy Jerusalem” is signified the Lord’s New Church, in like manner by the temple; and therefore by their “measurements” are signified states as to truth and as to good; as in John:

The angel had a golden reed, to measure the holy Jerusalem, and the gates thereof, and the wall thereof; and he measured the city with the reed, twelve thousand furlongs. And he measured the wall thereof, a hundred forty and four cubits, which is the measure of a man, that is, of an angel (Revelation 21:15-17).

That the “measurements” here signify states as to good and truth is very manifest, for the “holy Jerusalem” denotes the Lord’s New Church; “the gates and the wall” denote the protecting truths of faith; “twelve thousand” denotes all truths and goods in the complex; likewise “a hundred forty and four” (n. 7973), for this number signifies the like as the number “twelve” because it arises from twelve multiplied by twelve (that “twelve” denotes all truths and goods in the complex, see n. 577, 2089, 2129, 2130, 3272, 3858, 3913); “the measure of a man, that is, of an angel” signifies that such is the state of the church and of heaven in respect to the goods of love and the truths of faith, for “a man” denotes the church, and “an angel,” heaven. Unless it were known what is signified by “the holy Jerusalem,” by its “gate” and its “wall,” by the number “twelve thousand furlongs,” and by “the measure of the wall being a hundred forty and four,” also what by “measure,” what by “a man,” and what by “an angel,” who would ever know what is meant by “the measure of the city being twelve thousand furlongs,” and “the measure of the wall a hundred forty and four cubits, the measure of a man, that is, of an angel”?

[3] The like is signified by “measurement” in Zechariah:

I lifted up mine eyes again and saw a man in whose hand was a measuring line. I said, Whither goest thou? He said, To measure Jerusalem, to see what is the breadth thereof, and what is the length thereof (Zech. 2:1-2).

Also in Ezekiel, where a man who had a measuring reed measured the houses of the new city, and also the temple, as to the outer walls, the inner walls, the gates, the foundations, the thresholds, the windows, the steps (Ezekiel 40:0-42:0). Unless these measurements signified the states of the matter in respect to truth and good, such things would never have been mentioned. By “measuring” in general is signified the state of truth and good; as in Jeremiah:

Thus said Jehovah, If the heavens above shall be measured, and the foundations of the earth searched out beneath, behold still will I disapprove the seed of Israel for all that they have done. Behold the days come in which the city shall be built to Jehovah. And the measuring line shall go out more fully over the hill Gareb, and shall turn about unto Goah (Jeremiah 31:37-39).

Who hath measured the waters in His fist, and meted out the heavens with the span, and weighed the mountains in scales, and the hills in a balance? (Isaiah 40:12).
