87 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.
