54 Why doubt that body shall rise again from body? Grain is sown, grain comes up again: fruit is sown, fruit comes up again; but the grain is clothed with blossom and husk. “And this mortal must put on immortality, and this corruptible must put on incorruption.” The blossom of the resurrection is immortality, the blossom of the resurrection is incorruption. For what is more fruitful than perpetual rest? What supplied with richer store than everlasting security? Here is that abundant fruit, by whose increase man's nature shoots forth more abundantly after death.
