Tertullian

If sorrow, and mourning, and sighing, and death itself, assail us from the afflictions both of soul and body, how shall they be removed, except by the cessation of their causes, that is to say, the afflictions of flesh and soul? where will you find adversities in the presence of God? where, incursions of an enemy in the bosom of Christ? where, attacks of the devil in the face of the Holy Spirit?-now that the devil himself and his angels are "cast into the lake of fire." Where now is necessity, and what they call fortune or fate? What plague awaits the redeemed from death, after their eternal pardon? What wrath is there for the reconciled, after grace? What weakness, after their renewed strength? What risk and danger, after their salvation? That the raiment and shoes of the children of Israel remained unworn and fresh for the space of forty years; that in their very persons the exact point of convenience and propriety checked the rank growth of their nails and hair, so that any excess herein might not be attributed to indecency; that the fires of Babylon injured not either the mitres or the trousers of the three brethren, however foreign such dress might be to the Jews; that Jonah was swallowed by the monster of the deep, in whose belly whole ships were devoured, and after three days was vomited out again safe and sound; that Enoch and Elias, who even now, without experiencing a resurrection (because they have not even encountered death), are learning to the full what it is for the flesh to be exempted from all humiliation, and all loss, and all injury, and all disgrace-translated as they have been from this world, and from this very cause already candidates for everlasting life; -to what faith do these notable facts bear witness, if not to that which ought to inspire in us the belief that they are proofs and documents of our own future integrity and perfect resurrection? For, to borrow the apostle's phrase, these were "figures of ourselves; " and they are written that we may believe both that the Lord is more powerful than all natural laws about the body, and that He shows Himself the preserver of the flesh the more emphatically, in that He has preserved for it its very clothes and shoes.

But we do confess that a kingdom is promised to us upon the earth, although before heaven, only in another state of existence; inasmuch as it will be after the resurrection for a thousand years in the divinely-built city of Jerusalem, "let down from heaven," [Revelation 21:2] which the apostle also calls "our mother from above;" [Galatians 4:26] and, while declaring that our πολίτευμα, or citizenship, is in heaven, he predicates of it that it is really a city in heaven. This both Ezekiel had knowledge of [Ezekiel 48:30-35] and the Apostle John beheld. [Revelation 21:10-23] And the word of the new prophecy which is a part of our belief, attests how it foretold that there would be for a sign a picture of this very city exhibited to view previous to its manifestation. This prophecy, indeed, has been very lately fulfilled in an expedition to the East. For it is evident from the testimony of even heathen witnesses, that in Judæa there was suspended in the sky a city early every morning for forty days. As the day advanced, the entire figure of its walls would wane gradually, and sometimes it would vanish instantly. We say that this city has been provided by God for receiving the saints on their resurrection, and refreshing them with the abundance of all really spiritual blessings, as a recompense for those which in the world we have either despised or lost; since it is both just and God-worthy that His servants should have their joy in the place where they have also suffered affliction for His name's sake. Of the heavenly kingdom this is the process. After its thousand years are over, within which period is completed the resurrection of the saints, who rise sooner or later according to their deserts there will ensue the destruction of the world and the conflagration of all things at the judgment: we shall then be changed in a moment into the substance of angels, even by the investiture of an incorruptible nature, and so be removed to that kingdom in heaven of which we have now been treating, just as if it had not been predicted by the Creator, and as if it were proving Christ to belong to the other god and as if he were the first and sole revealer of it.
