All four gospels talk about John the Baptist and his fiery message of repentance. Two of the four gospels do not mention Jesus' birth at all. But Matthew, Mark, Luke, and John all recognized that no gospel would be complete without John the Baptist. A gospel may skip Christmas but it may not skip John. Why? Because as Zechariah knew already when John was just eight days old, John was going to be the necessary advance man to get the world ready to receive Jesus. If Jesus was the one who would plant the mustard seed of the kingdom into the soil of this world, then John was to be the one who did the hard work of plowing the soil to get ready for that planting. John would be the one who would sink down his plow blade into human hearts that were the spiritual equivalent of a parched field whose dirt had long ago hardened into something resembling concrete.

If Jesus was God's divine Visitor to this world, then John was the one who was sent to prepare the way. Because God knew and John the Baptist knew: how the visit of God's Son would be received would very much depend on people's situation. If they were eager to hear the good news that God's tender mercies were available to forgive their sins, then they'd be glad to hear just that message from the lips of Jesus. But if people didn't think they had a problem with sin, then the visit of God's Son would be merely annoying and a waste of their time. John worked overtime to ensure that no one had that reaction.
