Charles Spurgeon Commentary Jeremiah 1:9

"Then Jehovah put forth his hand, and touched my mouth; and Jehovah said unto me, Behold, I have put my words in thy mouth:" — Jeremiah 1:9 (ASV)

Then the LORD put forth his hand, and touched my mouth.

For you young brothers who are to be preachers of the gospel, I cannot wish anything better than that the Lord may touch your mouth in this way. In the old times that some of us remember, godly men used to pray that the Holy Spirit would be "mouth, matter, and wisdom" to the preachers of the Word. It was not at all a bad prayer, for it was a petition that He would give to His servants the right subject, the right spirit, and the right utterance—that He would teach them how to speak, what to speak, and in what spirit to speak it.

And the LORD said to me, Behold, I have put my words in your mouth.

That is a true picture of a Spirit-sent preacher of the gospel—a man who has God's words in his mouth. I said before that the minister must not utter his own thoughts, but here we see that he must not even utter his own words. God's thoughts are best delivered in God's words; and the more of Scripture there is in our teaching, the more true, the more divine, and the more powerful, will it be.
