“Is not My Word like as a fire? says the LORD; and like a hammer that breaks the rock in pieces?” Jeremiah 23:29.
As we noticed while reading the chapter, there were a great many pretenders in the times of Jeremiah, so that when the true Prophet of God came forth and declared, “Thus says the Lord,” he was met by false prophets who contradicted him and said something the very reverse of what he had to say and yet prefaced their utterance with the same declaration, “Thus says the Lord.” This, of course, tended very much to harden the hearts of the people against the Divine message, and it also grievously embarrassed Jeremiah. He hardly knew how to meet it—it seemed to checkmate him.
This evil also greatly grieved the Lord, for it was not according to His mind that these men should pretend to speak under His Inspiration and to speak as if they felt the burden of the Lord, when He had never sent them and they had not delivered His message. He therefore gave a test by which the true could be distinguished from the false. In the verse before our text, the Lord asks, “What is the chaff to the wheat?” That which these false prophets said was but chaff compared with the Divine message delivered by Jeremiah, which was as wheat—so the Lord puts the matter thus, “You hear these men speak and you are interested and pleased, and you say to yourselves, ‘This is fine oratory, this man has a grand way of speaking.’ You admire his style, his eloquence, his depth of thought and all that, but I say to you, ‘Is not My Word like as a fire?’ It comes not as a thing of beauty, but with force, with energy. It comes to you, not that you may stand and look at it, but it has within itself a burning and consuming force. And by this shall My Word be known from the word of man—that it has a mystic power about it which cannot be found in the words of men. And it is a breaking force, as when a mighty hammer strikes the rock, and strikes it again and again till even the solid granite is compelled to yield.”
