John 1:6

Verse 6. A man sent from God. See Matthew, Chapter 3. The evangelist proceeds now to show that John the Baptist was not the Messiah, and to state the true nature of his office. Many had supposed that he was the Christ, but this opinion he corrects; yet he admits that he was sent from God--that he was divinely commissioned. Though he denied that he was the Messiah, yet he did not deny that he was sent from or by heaven on an important errand to men. Some have supposed that the sole design of this gospel was to show that John the Baptist was not the Messiah. Though there is no foundation for this opinion, yet there is no doubt that one object was to show this.
