Part One: Follow me. A true disciple is following Christ
Part Two: And I will make you A disciple is being changed by Christ
 While walking by the Sea of Galilee, he saw two brothers, Simon (who is called Peter) and Andrew his brother, casting a net into the sea, for they were fishermen.  And he said to them, “Follow me, and I will make you fishers of men.”  Immediately they left their nets and followed him.
Fishers of men. A disciple taking up the mission of Christ.
With these words Jesus clarified the mission. Becoming a disciple means becoming interested in the eternal well-being of people. He says, “I’m going to change you. If you follow me, I’m going to make you something. Now you catch fish, soon you’ll catch people.” Let’s make it more modern. “Now you strive for As on your report card, soon you’ll strive for people. Now you strive for a successful career, soon you’ll strive for people. Now you’re building a platform, soon you’ll be building people. Now you strive for popularity, soon you’ll strive for people. Right now athletics are all-consuming, but there will be a day that the well-being of others consumes you.”
The underlying assumption is that the premiere sign of maturity is a genuine concern for other people. Jesus’s goal is to make them more interested in people than their careers. Jesus wants them to be more concerned about relationships than about their education, their status, their achievements, their awards, their scholarships, their accolades.
He didn’t say, “follow me and I will make you successful businessmen.” He didn’t say, “follow me and I will land you a good, well-paying job.” He didn’t say, “follow me and I will help you achieve your goals and dreams.” He says, “If you follow me, I’m going to reshape the way you see the world. I’m going to change your whole outlook on life. I’m going to show you that the greatest purpose you can give your life to is people.” Look at it this way: Jesus spent the last three years of his life with his people, teaching and training them to follow Christ. Your job is to do the same thing: spend your life with people teaching and training them to follow Christ. A true disciple is a disciple-maker.
If this is true, then we must understand that being relational is not an option, it’s a calling. The greatest thing we can give our lives to is relationships. The Bible speaks about two things lasting forever: God’s Word and people. Do you want to have a meaningful life? Do you want to labor for things that vanish like steam or for eternal treasures that never fade? Jesus’s call was to invest in the eternal—God’s Word and people. True disciples learn to do exactly that. They become “fishers of men.” That means, they orient their entire lives around this calling. They see that in order to be faithful they must give themselves to God’s Word and people.
So a true disciple is following Christ—believing, changing, submitting. He is being changed by Christ—learning and growing in grace. And he is taking up the mission of Christ—as a disciple-maker.
