The word of God came to John the son of Zacharias in the wilderness. And he went into all the region around the Jordan, preaching a baptism of repentance for the remission of sins. (Luke 3:2–3; NKJV)

God fulfilled His promise to Zacharias. The Holy Spirit was upon John, and now “the Word of God came to John” in a mighty way. Luke does not tell us how the Word of God came upon him. But the message John preached reveals at least some of what this Word of God to John contained. It was the message of repentance for the remission of sins and the announcement that Israel’s Messiah was coming very soon (vv. 15–17).
