We talk about laws of nature, and we say they are fixed and unchanging. Yes; but God is behind the laws of nature. They are merely his ways of working. They do not work and grind like a great heartless machine; there is a heart of love, a Father’s heart, at the centre of all this vast mechanism which we call nature. All things work together for good to every one who loves God. You are the centre of the universe in a sense that is wondrously true. All things revolve about you; all things minister to your good. If only you keep your trust fixed upon God, and are obedient and submissive even nature’s tremendous energies will never harm your true life.
