Isaias 65:18

4. Then again, speaking of Jerusalem, and of Him reigning there, Isaiah declares, “Thus saith the Lord , Happy is he who hath seed in Zion, and servants in Jerusalem. Behold, a righteous king shall reign, and princes shall rule with judgment.” And with regard to the foundation on which it shall be rebuilt, he says: “Behold, I will lay in order for thee a carbuncle stone, and sapphire for thy foundations; and I will lay thy ramparts with jasper, and thy gates with crystal, and thy wall with choice stones: and all thy children shall be taught of God, and great shall be the peace of thy children; and in righteousness shalt thou be built up.” And yet again does he say the same thing: “Behold, I make Jerusalem a rejoicing, and my people [a joy]; for the voice of weeping shall be no more heard in her, nor the voice of crying. …

2. Now all these things being such as they are, cannot be understood in reference to super-celestial matters; “for God,” it is said, “will show to the whole earth that is under heaven thy glory.” But in the times of the kingdom, the earth has been called again by Christ [to its pristine condition], and Jerusalem rebuilt after the pattern of the Jerusalem above, of which the prophet Isaiah says, “Behold, I have depicted thy walls upon my hands, and thou art always in my sight.” And the apostle, too, writing to the Galatians, says in like manner, “But the Jerusalem which is above is free, which is the mother of us all.” He does not say this with any thought of an erratic Æon, or of any other power which departed from the Pleroma, or of Prunicus, but of the Jerusalem which has been delineated on [God’s] hands. …

But because he said, “Your heart shall rejoice,” lest we should suppose that the blessings of that Jerusalem are only spiritual, he adds, “And your bones shall rise up like a herb,” alluding to the resurrection of the body, and as it were supplying an omission he had made. For it will not take place when we have seen; but we shall see when it has taken place. For he had already spoken of the new heavens and the new earth, speaking repeatedly, and under many figures, of the things promised to the saints, and saying,“There shall be new heavens, and a new earth: and the former shall not be remembered nor come into mind; but they shall find in it gladness and exultation. Behold, I will make Jerusalem an exultation, and my people a joy. …

Wherefore, not to mention many other instances besides, as we now see in Christ the fulfillment of that which God promised to Abraham when He said, “In thy seed shall all nations be blessed,” so this also shall be fulfilled which He promised to the same race, when He said by the prophet, “They that are in their sepulchres shall rise again,” and also, “There shall be a new heaven and a new earth: and the former shall not be mentioned, nor come into mind; but they shall find joy and rejoicing in it: for I will make Jerusalem a rejoicing, and my people a joy. And I will rejoice in Jerusalem, and joy in my people, and the voice of weeping shall be no more heard in her.” And by another prophet He uttered the same prediction: “At that time thy people shall be delivered, every one that shall be found written in the book. …

34. Finally, my brethren, rejoice in the Lord alway; again I will say, Rejoice: for your redemption hath drawn nigh , and the heavenly host of the Angels is waiting for your salvation. And there is now the voice of one crying in the wilderness, Prepare ye the way of the Lord ; and the Prophet cries, Ho, ye that thirst, come ye to the water ; and immediately afterwards, Hearken unto me, and ye shall eat that which is good, and your soul shall delight itself in good things . And within a little while ye shall hear that excellent lesson which says, Shine, shine, O thou new Jerusalem; for thy light is come . …

Moses . To cling to God continually, and as you say inseparably to hold fast to meditation on Him, is impossible for a man while still in this weak flesh of ours. But we ought to be aware on what we should have the purpose of our mind fixed, and to what goal we should ever recall the gaze of our soul: and when the mind can secure this it may rejoice; and grieve and sigh when it is withdrawn from this, and as often as it discovers itself to have fallen away from gazing on Him, it should admit that it has lapsed from the highest good, considering that even a momentary departure from gazing on Christ is fornication. And when our gaze has wandered ever so little from Him, let us turn the eyes of the soul back to Him, and recall our mental gaze as in a perfectly straight direction. …
