No, I tell you; but unless you repent, you will all likewise perish.
Imagine that there is a person who says they are a fan of the New England Patriots. They tell people all the time how much they love the Patriots and how Tom Brady is their favorite Quarterback. Maybe they even have a Patriots jersey that they like to sport at least once a week so people can see how crazy they about their football team.
But what if I told you that this person never watches the Patriots play, doesn’t really know how good Tom Brady is beyond what people tell them, and they don’t actually even like watching the game of football. Can they even really be a fan of the New England Patriots? Of course not!
Jesus in Luke 13 is telling us the same thing.
Jesus had just gotten done telling the crowds and the Pharisees to interpret the times. The kingdom of God is near and is coming soon. As a result, he is calling them to turn away from trusting in their heritage or in their good works to make them right with God, but instead they must repent. This literally means that they are to turn away from trying to get to God on their own and instead they must turn to Christ and his ways.
This idea of repenting or turning to Christ is so important that he reiterates it in verse 5 of this chapter.
 No, I tell you; but unless you repent, you will all likewise perish.”
So how does this relate to the New England Patriots fan who really isn’t a fan? Its simple. We often say that we are followers of Christ, and in fact many of the Jews in Jesus day would have said they were disciples of Christ. However, they didn’t really know who Jesus was, and they didn’t really want to follow him. Jesus talks about these kind of people when he says in Luke 13:26-27:
 Then you will begin to say, ‘We ate and drank in your presence, and you taught in our streets.’  But he will say, ‘I tell you, I do not know where you come from. Depart from me, all you workers of evil!’
The point? You can’t just look like a follower. Jesus is calling his people to believe that he is the Messiah, the Christ, and to live accordingly. To live our whole life in submission and service to him knowing that he is the only way, the only truth, and the only life.
This requires us to be more than a fake or far weather fan of Jesus. And it definitely requires us to do more than just have a Jesus jersey. Instead it requires us to know him, to spend time with him, to seek him on a daily basis, to confess and turn away from sin, to put all of our hope and trust in him, to follow him and his commands, and to proclaim his salvation and his kingdom until he returns.
So let’s examine ourselves and ask the question, am I really a follower or fan of Christ or am I just trying to make people think I am? Do I even really want to be a follower? If so, heed the words of Jesus:
Repent, turn away from your sin, trust him alone, and bear fruit for his kingdom.
