“In Isaiah 28:26 we read that God instructs the plowman, teaching him how he is to do his work. But this instruction does not come to the plowman in writing, in so many words, nor in the form of lessons at school; it is a teaching, rather, which is contained and expressed in all the laws of nature, in the character of air and of soil, of time and place, of grain and corn. What the plowman must do is conscientiously to get to know all those laws of nature, and in this way to learn the lesson which God teaches in them.”
