John 3:24

Obviously John continued preaching and baptizing after Jesus began ministering, and he did so until Herod Antipas imprisoned him. The Synoptic writers began their narratives of Jesus’ public ministry with His ministry in Galilee. They viewed the beginning of Jesus’ ministry as starting with John the Baptist’s imprisonment (Mark 1:14). The Apostle John began his narrative of Jesus’ ministry with His earlier Judean ministry. From him alone we learn that between Jesus’ temptation and John the Baptist’s arrest John and Jesus baptized at the same time. His reference to John the Baptist’s imprisonment is important because it helps the reader see that John’s account does not contradict the Synoptics. Yet his primary concern was John the Baptist’s witness to Jesus.
