After Satan leaves Jesus, Matthew turns to the beginnings of Jesus’ ministry. In this passage, we see his journey to Galilee, and the calling of his first disciples.
Matthew 4:12 tells us that Jesus heads to the region of Galilee. The reason for this destination is that his cousin, John the Baptist, had been thrown into prison. This likely weighed heavily on Jesus’ heart for two reasons, first, they were related, and second, John was the forerunner of Jesus, preparing the way for his ministry.
If we only had the Synoptic Gospels — Matthew, Mark and Luke — we would know very little about this event, and in fact, this entire period of time. The Synoptics skip a whole year of Jesus’ life and ministry, moving from the temptations to this trip to Galilee. Thankfully, we have John’s account to fill in some of the blanks. He covers this period in John 1:19-3:36. From the lack of information in the Synoptic three, we can assume that John may have been in prison for a year or more, and that Jesus’ ministry begins in earnest after his death.
