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. [19] And he said to them, “Follow me, and I will make you fishers of men.” Immediately they left their nets and followed him. And going on from there he saw two other brothers, James the son of Zebedee and John his brother, in the boat with Zebedee their father, mending their nets, and he called them. Immediately they left the boat and their father and followed him. (Matt 4:18-22)
The first requirement to be a disciple—a Christian—is to follow Jesus.
To follow involves three elements: belief, life-change, and submission.
Following Jesus requires belief in who he was and what he came to do. Simon Peter and Andrew weren’t asked to follow someone they didn’t know. They had spent time with Jesus previously (John 1:35-42), and even believed he was the Messiah. When Jesus approached them in Matthew 4, they had already known Jesus for some time, scholars say a year. So we understand that the first requirement of a disciple of Jesus Christ is to believe.
Of course, the Simon Peter and Andrew didn’t know a lot about Jesus. But they believed he was the Messiah, even though they didn’t entirely understand. And this is the beauty of following Jesus—you don’t have to be a genius to figure it out. Your understanding of Jesus doesn’t have to complete. In fact, usually it’s the simple ones who get it best. “God chooses the foolish to shame the wise.” You can’t follow someone you don’t believe.
What you do have to know is that you have a sin problem that has earned you punishment and Jesus alone can save you. There are more details—a glorious and beautiful treasure trove of details—but the essentials of following Jesus today remain quite simple. God made you. You rebelled. Faith in Christ saves those who repent and believe. Those who believe those things are saved.
Following Jesus also implies life change. When Jesus says “follow me” the underlying directive is stop following that. If he says follow me, he means give up on your ways. If he says live for me, he means stop living for yourself. Simon and Andrew got it—they left their nets and followed him. Following Christ meant giving up their careers in fishing. James and John were mending their nets, trying to fix them so they could catch more fish. And suddenly when Jesus called them, they left the nets in the boat. They weren’t important anymore—following Jesus meant leaving behind old ways.
That’s what following Jesus is—not literally following him around, like the original disciples did. For us, following him has a much broader meaning: we are to follow his way of life, his teachings, his priorities, his goals.
Following Jesus also indicates submission. Jesus says follow me, and that means we give up the rights to run our lives. This is called repentance. We have handed over the title deed of our lives. We gladly submit to Jesus as our lord, master, leader, and guide.
Some try to make Jesus’s call easier than it actually was. They like to accept Jesus as Savior but not as Lord or Master. And so they think they’ll can be saved without submitting to Christ. This isn’t so—the truth is that if Jesus ain’t your Master he ain’t your Savior. If you haven’t submitted you haven’t been saved. It’s the blunt truth that Scripture is careful to repeat over and over again.
So let me recap quickly: When Jesus says “follow me” this is what he means: believe me, make a change in direction, and submit completely.
When Jesus said “I will make you” the offer was out on the table. Jesus was being straightforward. His intention was to make them into something they were not. Jesus wanted to fundamentally change their priorities, their desires, their goals, their dreams, their purposes—and he was clear about it. It was like he said, “I know you’ve spent your life catching fish. Not anymore. I’m going to change you.” To our modern ears, that sounds offensive. What right does he have? We shouldn’t try to change people, that’s rude. Let them be, man. Tolerate.
Jesus didn’t fit it then and he probably wouldn’t fit in now. His goal—and he was absolutely unashamed of it—was to change people. To make them into something they weren’t. From the beginning, this was laid out on the table. A disciple, then, is something who is being changed by Christ.
If you are to start following Christ—by believing, by changing, and by submitting—you must understand what you’re agreeing to. Almost everything you sign up for these days has a long tedious document with terms and conditions. Does anyone actually read those? Well, Jesus has terms and conditions that we must agree to if we are to follow him. But they’re not long, hard to read, annoying and complicated. They’re actually simple. He says” if you follow me, understand this: I am going to change you. That means you must be eager to learn and eager to change.”
True disciples are learners. People who think they have nothing else to learn aren’t good disciples. The best disciples are the best learners. They are hungry for knowledge, hungry for information, hungry for insight, hungry for wisdom, hungry to acquire skill, hungry to hone their talents, hungry to practice what they’ve been taught. Part of what it means to follow Jesus is admitting you not only have the deep-seated problem of sin, but the deep need of being taught.
True disciples want to change. This goes right along with being a learner, but it takes it to the next level. Being a true disciple means not only learning but practicing what you’re learning. True disciples aren’t about acquiring information for information’s sake. They want to change. They hate their sin and they want to grow. That’s why Jesus’s call must have been so appealing. I love it—Jesus promises to change them. “I will make you.” Perk up whenever Jesus makes an “I will” statement. He said to his disciples that he would make them fishers of men. He would set out to change them and he wouldn’t fail. This is great hope for us, because the promise we receive is that Jesus will change us to make us useful for his service as we follow him.
So a true disciple is following Jesus and eager to learn and change. And he is also someone being changed by Christ. He is radically in love with Jesus and willing to submit to whatever and wherever the Master commands him
