If the earth and heaven are renewed, why should we doubt that man, on account of whom heaven and earth were made, can be renewed? If the transgressor be reserved for punishment, why should not the just be kept for glory? If the worm of sins does not die, how shall the flesh of the just perish? For the resurrection, as the very form of the word shows, is this, that what has fallen should rise again, that which has died should come to life again.

And this is the course and ground of justice, that since the action of body and soul is common to both(for what the soul has conceived the body has carried out), each should come into judgment, and each should be either given over to punishment or reserved for glory. For it would seem almost inconsistent that, since the law of the mind fights against the law of the flesh, and the mind often, when sin dwelling in man acts, does that which it hates; the mind guilty of a fault shared by another should be subjected to penalty, and the flesh, the author of the evil, should enjoy rest: and that should alone suffer which had not sinned alone, or should alone attain to glory, not having fought alone with the help of grace.

The reason, unless I am mistaken, is complete and just, but I do not require a reason from Christ. If I am convinced by reason I reject faith. Abraham believed God, let us also believe Him, that we who are heirs of his race may also be heirs of his faith. David likewise believed, and therefore did he speak; let us also believe that we may be able to speak, knowing that “He Who raised up the Lord Jesus shall raise up us also with Jesus.” For God, Who never lies, promised this; the Truth promised this in His Gospel, when He said: “This is the will of Him that sent Me, that of all that which He hath given Me I should lose nothing, but should raise it up at the last day.” And He thought it not sufficient to have said this once, but marked it by express repetition, for this follows: “For this is the will of My Father, Who sent Me, that every one that seeth the Son and believeth on Him should have eternal life, and I will raise him up at the last day.” — Two Books on the Decease of His Brother Saytrus – Book II, para. 87-89.
