He came into all the region around the Jordan, preaching the baptism of repentance for remission of sins.
      1. The origin of it was from heaven: The word of God came unto John,Luke 3:2; Luke 3:2. He received full commission and full instructions from God to do what he did. It is the same expression that is used concerning the Old-Testament prophets (Jeremiah 1:2); for John was a prophet, yea, more than a prophet, and in him prophecy revived, which had been long suspended. We are not told how the word of the Lord came to John, whether by an angel, as to his father, or by dream, or vision, or voice, but it was to his satisfaction, and ought to be to ours. John is here called the son of Zacharias, to refer us to what the angel said to his father, when he assured him that he should have this son. The word of the Lord came to him in the wilderness; for those whom God fits he will find out, wherever they are. As the word of the Lord is not bound in a prison, so it is not lost in a wilderness. The word of the Lord made its way to Ezekiel among the captives by the river of Chebar, and to John in the isle of Patmos. John was the son of a priest, now entering upon the thirtieth year of his age; and therefore, according to the custom of the temple, he was now to be admitted into the temple-service, where he should have attended as a candidate five years before. But God had called him to a more honourable ministry, and therefore the Holy Ghost enrols him here, since he was not enrolled in the archives of the temple: John the son of Zacharias began his ministration such a time.
