89. Furthermore, in noble men, who check and control these impulses, it calls them virtues; in others who give the reins to their desires, it calls them vices. This is nothing less than ignorance of the fact that human nature is evil. The Scriptures, on the contrary agree with our experience and declare that the human heart is evil from youth. For we learn by experience that even holy men can scarcely stand firm; yea that even they are often entangled by gross sins, being overwhelmed by such natural corruptions. 90. The term _ne-urim_ denotes the age when man begins to use his reason; this usually occurs in the sixth year. Similarly, the term _ne-arim_ is used to denote boys and youths who need the guidance of parents and teachers up to the age of manhood. It will be profitable for each of us to glance backward to that period of life and consider how willingly we obeyed the commands of our parents and teachers, how diligent we were in studying, how persevering we were, how often our parents punished our sauciness. Who can say for himself that he was not much more pleased to go out for a walk, to play games, and to gossip, than to go to Church in obedience to his parents? 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._
