But perhaps nature if more deeply investigated will seem to give a deeper reason for our belief: let our thoughts turn back to the origin and commencement of the creation of man. You are men and women, you are not ignorant of the things which have to do with human nature, and if any of you have not this knowledge, you know that we are born of nothing. But how small an origin for being so great as we are! And if I do not speak more plainly, yet you understand. what I mean, or rather what I will not say. Whence, then, is this head, and that wonderful countenance, whose maker we see not? We see the work, it is fashioned for various purposes and uses. Whence is this upright figure, this lofty stature, this power of action, this quickness of perception, this capacity for walking upright? Doubtless the organs of nature are not known to us, but that which they effect is known. Thou too wast once seed, and thy body is the seed of that which shall rise again. Listen to Paul and learn that thou art this seed: “It is sown in corruption, it shall rise in incorruption; it is sown in dishonour, it shall rise in glory; it is sown in weakness, it shall rise in power; it is sown a natural body, it shall rise a spiritual body.” Thou also, then, art sown as are other things, why wonderest thou if thou shall rise again as shall others? But thou believest as to them, because thou seest; thou believest not this, because thou seest it not: “Blessed are they that have not seen, and yet have believed.”

However, before the season comes, those things also are not believed, for every season is not suited for the raising of seeds. Wheat is sown at one time, and comes up at another; at one time the vine is planted, at another the budding twigs begin to shoot, the foliage grows luxuriant, and the grape is formed; at one time the olive is planted, at another time, as though pregnant and loaded with its offspring of berries, it is bent down by the abundance of its fruit. But before its own period arrives for each, the produce is restricted, and that which bears has not the age of bearing in its own power. One may see the mother of all at one time disfigured with mould, at another bare of produce, at another green and full of flowers, at another dried up. Any spot which might wish to be always clothed and never to lay aside the golden dress of its seeds, or the green dress of the meadows, would be barren in itself and unendowed with the gain of its own produce which it would have transferred to others.

So, then, even if thou wilt not believe in our resurrection by faith nor by example, thou wilt believe by experience. For many products, as the vine, the olive, and different fruits, the end of the year is the fit time for ripening; and for us also the consummation of the world, as though the end of the year has set the fitting time for rising again. And fitly is the resurrection of the dead at the consummation of the world, test after the resurrection we should have to fall back into this evil age. For this cause Christ suffered that He might deliver us from this evil world; lest the temptations of this world should overthrow us again, and it should be an injury to us to come again to life, if we came to life again for sin. — Two Books on the Decease of His Brother Saytrus – Book II, para. 60-62.
