John was a prophet whose ministry was rooted in the Old Testament. John did not merely fulfill Old Testament prophecy, he spoke as an Old Testament prophet. John and the Old Testament prophets spoke of the future, of the Kingdom of God, of the Messiah, and of “things to come” in two different ways. The prophets spoke of the coming of the Lord both as a time of judgment and as a time of blessing. They spoke of Messiah both as the great King, who would reign from the throne of David, and as the Suffering Servant, who would die for the sins of the world. And, you will recall, this was the cause for considerable interest and even agony on the part of the prophets.
