In this passage, the Lord God of heaven condescend not only to offer the sweetest of mercies with freeness of his grace, but pleads those who hear to take his offer seriously. As part of his mighty reasoning, he moves from a natural likeness to a supernatural process. He speaks of the gift from heaven of rain and snow that do not return but water the ground, bringing both seed and bread, and likens it to the word which proceeds from his mouth to men's hearts, accomplishing his saving purposes. This is, to us, a word of affirmation, a ground of conviction, a point of instruction, a spur to supplication, a note of consolation, and a prompt to expectation.
