Tertullian

“ Now that life is not yet apprehended which is hidden. In like manner John says: “And it doth not yet appear what we shall be: we know, however, that when He shall be manifest, we shall be like Him.” [8] We are far indeed from being already what we know not of; we should, of course, be sure to know it if we were already (like Him) . It is therefore the contemplation of our blessed hope even in this life by faith (that he speaks of) —not its presence nor its possession, but only its expectation. ”

“ Concerning this expectation and hope Paul writes to the Galatians: “For we through the Spirit wait for the hope of righteousness by faith.” [9] He says “we wait for it,” not we are in possession of it. By the righteousness of God, he means that judgment which we shall have to undergo as the recompense of our deeds. It is in expectation of this for himself that the apostle writes to the Philippians: “If by any means,” says he, “I might attain to the resurrection of the dead. ”

“ Now, since he makes us spiritually dead—in such a way, however, as to allow that we shall one day have to undergo a bodily death,—so, considering indeed that we have been also raised in a like spiritual sense, he equally allows that we shall further have to undergo a bodily resurrection. ”
