91. Although these impulses can be corrected or bridled to a certain extent by discipline, they cannot be rooted out of the heart altogether, as the traces of these impulses show when we are grown. There is truth in that unpolished lie: "The angelic youth becomes satanic in his older years." God, indeed, causes some persons to experience emotions which are naturally good; but they are induced by supernatural power. Thus Cyrus was impelled to restore the worship of God, and to preserve the Church. But such is not the tendency of human nature. Where God is present with his Holy Spirit, there only, the imagination of the human heart gives place to the thoughts of God. God dwells there through the Word and the Spirit. Of such, Moses does not speak here, but only of those who are without the Holy Spirit; they are wicked, even when at their best.
V. 21e. Neither will I again smite any more everything living, as I have done.
92. Moses clearly speaks of a general destruction, like that which was caused by the flood. From this it does not follow that God will also abstain from partial destruction, and that he will take no heed of anybody's sin. There will also be an exception in the case of the last day, when not only all living things will be smitten, but all creation will be destroyed by fire.
V. 22. While the earth reigneth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.
93. Following this text, the Jews divide the year into six parts, each comprising two months, a fact which Lyra also records in this connection. But it seems to me that Moses simply speaks of the promise that we need not fear another general flood. During the time of the flood such confusion reigned that there was no season, either of seedtime or harvest, and by reason of the great darkness caused by the clouds and the rain, day could not readily be distinguished from night. We know how heavy clouds obscure the light. How much greater, then, was the darkness when the waters, lying under the clouds like a mirror, reflected the darkness of the clouds into the faces and eyes of the beholders!
94. The meaning, accordingly, is simply that God here promises Noah the imminent restoration of the earth, so that the fields might again be sowed; that the desolation caused by the flood should be no more; that the seasons might run their course in accordance with regular law: harvest following seedtime, winter following summer, cold following heat in due order.
