Thy words were found, and I did eat them… – Jeremiah 15:16

Thy words were found, and I did eat them.” It is not “I did hear them,” for that he might have done, and yet have perished. Herod heard John gladly, and yet became his murderer. He does not say, “I did learn them by heart”- hundreds have committed chapters to memory and were rather wearied than benefited thereby. The Scribes fought over the jots and titles of the law but were blind leaders of the blind notwithstanding. It is not “Thy words were found, and I did repeat them,” for that he might have done as a parrot repeats language it is taught: nor is it even, “Thy words were found, and I remembered them;” for though it’s an excellent thing to store truth in the memory, yet the blessed effect of the divine words comes rather to those who ponder them in their hearts. “Thy words were found, and I did eat them.” What is meant by eating God’s words? The phrase signifies more than any other word could express. It implies an eager study-“I did eat them.” He who loves the Savior desires to grow in knowledge of Him; he cannot read or hear too much or too often concerning his great Redeemer. He turns to the holy page with ever new delight; he seeks the blessing of the man who meditates in God’s law both day and night. The stamp of divine authority upon any teaching is enough for the believer. Proud self-will demands to have doctrines proved by reasoning, but faith lets the declaration of Jehovah stand in the place of argument. We are committed to revelation, our minds are made up; we confess that we have eaten God’s word and intend still to feed upon it-upon the whole of it, and upon nothing else. ~ C.H. Spurgeon
