John the Baptist in the Gospels
Though we tend to conflate the four gospels, they actually have different presentations of John the Baptist. For instance, in the Gospel of Luke, John the Baptist preaches much more directly to the crowd than in the other gospels. Therefore, more is learned about John's message in the Gospel of Luke. In the Gospel of Matthew, we learn more about Jesus' direct interaction with John the Baptist. For example, when John insisted that Jesus should be baptizing him and not the other way around. And in Mark, we get the clearest glimpse of just how counter-cultural John was in his clothing and demeanor.
The Gospel of John, though, is particularly unique. In the Gospel of John, John the Baptist is actually, more accurately described as, "John the Witness." His primary role isn't as the Baptizer of Jesus. Instead, John points to Jesus as the lamb of God. John the Witness takes whatever authority he has and uses it to testify to Jesus' authority. By doing so, John serves as a model for each and every disciple of Jesus.
As Jesus' disciples, we are to be witnesses to him. Our lives should point to him so that others may know who he is. In what ways does your life point to Jesus?
