John Chrysostom : God's purpose, therefore, was to eliminate all apprehension from Noah's thinking and for him to be quite assured that this would not happen again. He said, remember, "Just as I brought on the deluge out of love, so as to put a stop to their wickedness and prevent their going to further extremes, so in this case too it is out of my love that I promise never to do it again, so that you may live free of all dread and in this way see your present life to its close." Hence he said, "Behold, I make my covenant," that is, I form an agreement. Just as in human affairs when someone makes a promise he forms an agreement and gives a firm guarantee, so too the good Lord said, "Behold, I make my covenant." God did not say that this massive disaster might come again to those who sin. Rather he said, "Behold, I make my covenant with you and your offspring after you." See the Lord's loving kindness: not only with your generation, he says, do I form my agreement, but also in regard to all those coming after you I give this firm guarantee. — HOMILIES ON Genesis 28.4
