Jeremiah 26:12

The Lord sent me to prophesy... — The answer of the accused is that of all true prophets and preachers of the word, “The Lord God hath spoken, and he can but prophesy” (Amos 3:8). He must “obey God rather than man” (Acts 5:29). And in this instance the prophet has nothing in the way of credentials but the message itself. He worked no signs or wonders.
