If God should stay His hand for a moment, human life would cease. God is no absentee landlord who made the world as a clock, able to run of itself when wound up. The creation account in Genesis teaches that, in himself, man is only dust. God is a God of law, and He rules His created domain by law. Everything from the stars in their courses to the smallest mote floating in the summer breeze operates within the boundaries of law.
Law governs the movement of planetary bodies, the growth of plants and the habits of animals.
There are laws of motion, sound and temperature, laws of chemical action and reaction, laws of mathematics, physics and heredity. Man is subject to these laws too. He has nothing to do with arranging them, because the laws of life are givens. Without law, existence would not only be precarious and unpredictable, but impossible. We would have no freedom to take one foot off the ground or to plan an hour ahead unless we could be sure that all objects are subject to gravity and that each hour measures sixty minutes.
