There are two lessons taught in these words:
I. God works by means. God makes all the means, and then uses them as He sees good. God is not obliged to work by means. Sometimes, as we learn from the Bible, He is pleased to work miracles, just to show us His power and teach us that all things obey His will. But that is very seldom. Most things God does by using the proper means, not because He is obliged, but because it is the best and wisest plan, and He has made all things on purpose.
II. All things do God's will, just as much as if He did everything by miracle all things.But do all people? Do you?
Can you say that you obey all that God tells you in His word as swiftly and as perfectly as the snow melts before the fire? Alas! no. Nobody can say this, for even when we try our best to please God we find that we fail; and our obedience is imperfect, just as if the snow were only half to melt, and be all mixed up with little bits of warm ice that refused to melt. God wishes you to obey Him not as the snow, and winds, and clouds, and sunshine obey Him because they cannot help it but willingly, because you love Him.
