At the start of any project, there is a key moment when the thing you are doing moves from something that COULD happen into something that IS happening. At lot of people get stuck in the dreaming phase and never really begin anything of substance because they cannot imagine going from the “anything is possible” part to the “this is what I’m going to actually do” part. Thankfully, Jesus’ ministry did not just stay in the design board. He has a specific place and time to start the mission that He came to fulfill. As Jesus begins His ministry, He gets baptized by His cousin, John the Baptist. Other Gospels include more detail on this event, but Luke mentions it to show how God made it clear that Jesus was about to get to work. In this event, there is a real symbol (one we still use today) for what it means to be saved. And of course, Luke makes sure to capture all the details that make it clear this Man is going to fulfill the salvation prophecies that the Jews had been reading all their lives.
