In the fifteenth year of the reign of Tiberius Caesar—when Pontius Pilate was governor of Judea, Herod tetrarch of Galilee, his brother Philip tetrarch of Iturea and Traconitis, and Lysanias tetrarch of Abilene— during the high priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the desert. He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins. As is written in the book of the words of Isaiah the prophet:
“A voice of one calling in the desert, ‘Prepare the way for the Lord. . . ” (Luke 3:1-4)
We have to ask ourselves why such a passage would be in the Bible. The section listing the leaders adds no theological point, no spiritual truth, no church law, no personal edification, no religious end. Other spiritual books from the era do not include such passages. Why would someone include such a thing?
We can prove the leaders in this section lived in the times and had the titles listed here. Since we can prove the parts we can corroborate, it only makes sense to accept the things we cannot prove, which was that John the Baptist actually spoke in the wilderness and said the things he did. We accept the passages we cannot prove because the passages we can prove are so accurate.
But further, this is tying Jesus to a passage in Isaiah 40. Isaiah says to “prepare the way for the LORD” which uses the name of God almighty. Prepare the way for YHWH, Jehovah God. John the Baptist, inspired by God, is calling Jesus God Almighty.
We have no way around passages such as this other than to accept them as they are: a factual historical account of a prophet of God who was telling us that Jesus was the one and only Deity.
