_As those who have been born again._ Again we should do this, because we are not what we were before (he says), but have become new creatures. This has not come to pass through works, but is a consequence of the new birth. For thou canst not make the new man, but he must grow, or be born; as a husbandman cannot make a tree, but it must grow, itself, out of the earth, and as we certainly do not become the children of Adam, except as we are born and derive sin from our parents. So here it cannot come to pass through works that we should become the children of God, but we must also experience the new birth. This, therefore, is what the Apostle would say: since ye then have become new creatures, ye should conduct yourselves otherwise than ye did, and lead a new life. As ye before lived in hate, ye are now to walk in love--in all respects the reverse. But how has the new birth taken place? This, also, follows: V. 23. _Not of corruptible, but of incorruptible seed, even of the living word of God which endures for ever._ Through a seed are we born again, for nothing grows as we see otherwise than through seed. Did the old birth spring from a seed? then must the new birth also spring from a seed. But what is this seed? Not flesh and blood! What then? It is not corruptible, but an eternal word. It is, moreover, that whereon we live,--food and nourishment. But especially is it the seed whereby we are born again, as he here says. But how does this take place? After this manner: God lets the word--the Gospel--go forth, and the seed falls in the hearts of men, and wherever it fastens on the heart the Holy Spirit is present, and makes a new man; then the man becomes another, of other thoughts, of other words and works. Thus you are entirely changed. All that you before avoided you now seek out, and what you before sought after that you fly from. In respect to the birth of the body, it is the case that when conception takes place the seed is changed, so that it is seed no longer. But this is a seed which cannot be changed; it remains for ever; it changes me, so that I am transformed in it, and whatever is evil in me passes away from my nature. Therefore it is indeed a wonderful birth, and of extraordinary seed.--Now St. Peter says, further: V. 24, 25. _For all flesh is grass, and all the glory of man like the flower of grass; the grass withereth, and the flower thereof falleth away, but the word of the Lord endureth for ever._ This passage is taken from the prophet Isaiah, xl., where the prophet speaks in this manner: "Cry! what shall I cry? Cry thus: all flesh is grass, and all its glory like a flower of the field; the grass withereth and the flower falleth away, but the word of God endureth for ever." These words St. Peter introduces here; for this is, as I have said, a rich epistle, and well spiced with Scripture.
