This is John's testimony, when the Jews sent priests and Levites from Jerusalem to ask him, "Who are you?"
      [3.] He gives such an account of himself as might be profitable to them, and might excite and awaken them to hearken to him; for he was the voice (see Isaiah 40:3), a voice to alarm, an articulate voice to instruct. Ministers are but the voice, the vehicle, by which God is pleased to communicate his mind. What are Paul and Apollos but messengers? Observe, First, He was a human voice. The people were prepared to receive the law by the voice of thunders, and a trumpet exceedingly loud, such as made them tremble; but they were prepared for the gospel by the voice of a man like ourselves, a still small voice, such as that in which God came to Elijah, 1 Kings 19:12. Secondly, He was the voice of one crying, which denotes, 1. His earnestness and importunity in calling people to repentance; he cried aloud, and did not spare. Ministers must preach as those that are in earnest, and are themselves affected with those things with which they desire to affect others. Those words are not likely to thaw the hearers' hearts that freeze between the speaker's lips. 2. His open publication of the doctrine he preached; he was the voice of one crying, that all manner of persons might hear and take notice. Doth not wisdom cry?Proverbs 8:1. Thirdly, It was in the wilderness that this voice was crying; in a place of silence and solitude, out of the noise of the world and the hurry of its business; the more retired we are from the tumult of secular affairs the better prepared we are to hear from God. Fourthly, That which he cried was, Make straight the way of the Lord; that is, 1. He came to rectify the mistakes of people concerning the ways of God; it is certain that they are right ways, but the scribes and Pharisees, with their corrupt glosses upon the law, had made them crooked. Now John Baptist calls people to return to the original rule. 2. He came to prepare and dispose people for the reception and entertainment of Christ and his gospel. It is an allusion to the harbingers of a prince or great man, that cry, Make room. Note, When God is coming towards us, we must prepare to meet him, and let the word of the Lord have free course. See Psalms 24:7.
