In the first miracle of Jesus in John, we learn a lot about the nature of Christ. Jesus is God. Changing water into wine by instructing some waiters is a powerful demonstration. It is clearly supernatural. Jesus begins to reveal His divinity here. His disciples, seeing this, go from followers to believers.
But Jesus is also man. The interaction with Mary is almost comical. One imagines the typical mother, pushing her son to do something for her, whether he wants to or not. Jesus protests, but complies with what she wants. What son wouldn’t? She knows who He is (as we see in Luke’s account) and we can assume she has seen His power and glory o display before this event.
More than anything else here, we see Jesus’ humanity… No, that isn’t the right word, because the aspect of mankind that we see on display here is part of what it means to be created in God’s image. We see Jesus’ compassion. Jesus doesn’t need to do this miracle. It doesn’t quite fit strategically into His mission. It isn’t healing a sickness or saving a life. The couple could have merely run out of wine and closed their celebration down earlier than socially expected. What is a little embarrassment in light of all the wrongs Jesus came to make right? But Jesus cares about people. These are His friends and townsfolk.
Jesus cares about us too. He provides not only for our needs, He blesses us as well.
