The upside-down kingdom is the reign of God that Jesus announced in Mark 1:14-20. It is a kingdom where ordinary people are invited to follow a King who serves, where greatness is measured by sacrifice, and where everyone enters the same way: by repenting and believing the good news. Jesus didn’t recruit religious elites. He called fishermen to leave their nets and join his mission.
Setting the Scene in Mark 1:14-20
After his baptism and temptation, Jesus returned north to Galilee. It was his home region, a fertile area dotted with small towns around a freshwater lake about 13 miles long and 8 miles wide. Galilee was ruled by Herod Antipas, the same Herod who had just arrested John the Baptist. It also had a mixed population of Jews and Gentiles, which is why Isaiah once called it “Galilee of the nations” (Isaiah 9:1).
Fishing was a major industry around the Sea of Galilee. Towns like Capernaum and Bethsaida depended on it, and fish from the lake were salted and shipped across the region. That is the world Jesus walked into when he began his public ministry. He didn’t start in the temple courts of Jerusalem. He started on the shoreline, among working people.
The King’s Announcement
Mark summarizes Jesus’ message in just a few words, but every phrase carries weight.
Mark 1:14-15 After John was put in prison, Jesus went into Galilee, proclaiming the good news of God. “The time has come,” he said. “The kingdom of God has come near. Repent and believe the good news!”
“The time has come” uses the Greek word kairos, which doesn’t mean clock time. It means a decisive moment, an opportunity that has finally arrived. For centuries, God’s people had waited for him to keep his promises. Now Jesus says the wait is over. “The kingdom of God has come near” means God’s reign was breaking into the world in a new way through Jesus himself. Every time he healed someone or drove out a demon, he was showing what life looks like under God’s rule.
Imagine a government where every official was completely good. No corruption, no power grabs, no foolishness. That is a small picture of God’s kingdom. Because God is good, his reign is a blessing to everyone who welcomes it. Because he is righteous, it is also a threat to evil. The kingdom has already arrived in Jesus, it grows as people follow him, and it will be complete when he returns.
So what keeps people from welcoming that kind of King? Usually, it is the fact that we already have one. We like running “the kingdom of me.” That is why Jesus called people to repent, turning from a self-directed life, and to believe, trusting God’s promise through him. At this point in Mark, readers haven’t yet learned about the cross and resurrection. But the foundation is already clear: you can’t follow a new King while insisting on staying on the throne yourself.
The King’s Unlikely Team
Right after announcing the kingdom, Jesus starts building his team. And he goes about it in a surprising way.
Mark 1:16-18 As Jesus walked beside the Sea of Galilee, he saw Simon and his brother Andrew casting a net into the lake, for they were fishermen. “Come, follow me,” Jesus said, “and I will send you out to fish for people.” At once they left their nets and followed him.
In first-century Judaism, students usually chose their rabbi. A young man who wanted to learn would seek out a respected teacher and ask to study under him. Jesus flipped that pattern. He took the initiative and called his disciples himself. He also didn’t go looking for the best and brightest students from the religious schools. He chose fishermen in the middle of their workday. Later, the religious leaders would be astonished at Peter and John, noticing they were “unschooled, ordinary men” who “had been with Jesus” (Acts 4:13).
The phrase “fish for people” is a clever play on their trade, but it may also echo the prophet Jeremiah, who described God sending out “fishermen” to gather his people (Jeremiah 16:16). Jesus didn’t just tell them to change careers. He promised to change them: “I will send you out.” He takes responsibility for shaping the people he calls. That is the best answer to the objection, “I could never do that.” You don’t have to. Jesus will make you into what he calls you to be.
A quick look ahead in Mark shows these men were far from ready. They would argue about who was the greatest, misunderstand Jesus’ mission, and eventually abandon him. Jesus knew all of that when he called them. His choice wasn’t based on their performance but on his grace. Paul later explained why God works this way.
1 Corinthians 1:27-29 But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. God chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are, so that no one may boast before him.
That is good news for anyone who feels unqualified. God isn’t looking for impressive résumés. He delights in using ordinary people so that everyone can see the power is his. If Jesus could build his church on a handful of fishermen, he can use you right where you are.
The Cost of Following
Simon and Andrew left their nets “at once.” Then Jesus called James and John, and their response was just as immediate.
Mark 1:19-20 When he had gone a little farther, he saw James son of Zebedee and his brother John in a boat, preparing their nets. Without delay he called them, and they left their father Zebedee in the boat with the hired men and followed him.
This detail is easy to miss: Zebedee had “hired men.” This was a family business with employees, not a struggling side hustle. James and John walked away from financial security and their father’s company to follow a traveling teacher. Following Jesus cost them something real.
That is the heart of the upside-down kingdom. Later in Mark, Jesus will explain that in his kingdom, “whoever wants to become great among you must be your servant,” because he himself came “to serve, and to give his life as a ransom for many” (Mark 10:43-45). New Testament scholar Mark Strauss observes that this is the essence of Mark’s story: the mighty Messiah came not to conquer Rome but to suffer as a ransom for sin, and his disciples are called to follow the same path of self-giving service.
Mark 8:34 Then he called the crowd to him along with his disciples and said: “Whoever wants to be my disciple must deny themselves and take up their cross and follow me.”
For some people, following Jesus means leaving a career, like these first disciples. For most, it means following him right where they are: at work, at home, in their neighborhood. But for everyone, it means surrender. We trust a surgeon enough to go under anesthesia. Jesus is a King worthy of even greater trust. And following him always includes joining his mission to help others follow him too.
The Takeaway
The meaning of Mark 1:14-20 is that God’s kingdom has arrived in Jesus, and he invites ordinary people to enter it by repenting and believing. In this upside-down kingdom, the King serves, the unqualified are called, and true greatness looks like surrender. Jesus is still saying, “Come, follow me.”
