60 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 your body is the seed of that which shall rise again. Listen to Paul and learn that you are 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 do you wonder if you shall rise again as shall others?
But you believe as to them, because you see, you believe not this, because you see it not: “Blessed are they that have not seen, and yet have believed.”
