NOTES for Isa 40:25-31
What the prophet Isaiah says was once formulated very simply by a four-year-old boy. He reasoned approximately this way: God created the sea, the sky, trees, and the human being. The human being made the car, the house, and the airplane. If God created such things, then He has intelligence and uses it. But what He made is very different from what I make; therefore His intelligence is stronger than mine. And how much stronger, I cannot measure.
The simplicity of children's explanations is something the Lord constantly calls us to learn. Is the text of the prophet Isaiah difficult? Of course it is; and when you are exhausted and weary, you are not thinking about the greatness of God, or about realizing that He has His own ways for you. It is hard to acknowledge that He is smarter, higher, and wiser than a human being, and to accept this fact not only with the head but with the heart. Yet simple and open observation of the world allows us to discern this fact and accept it.
