To understand how to become a disciple of Jesus Christ, it makes most sense to start where Jesus started. While it is true that He said to the disciples, “Follow me, and I will make you fishers of men” (Matt. 4:19), the Bible records one message He proclaimed before that. In Matthew 4:17, Jesus said, “Repent, for the kingdom of heaven is at hand.”
Try taking this phrase literally. If someone warned you to be prepared because a king and his army were coming, what would you do? You would make sure you were ready to face him. If you weren’t prepared to fight this king, then you would do whatever it took to make peace with him.
The word repent means “to turn.” It has the idea of changing directions and heading the opposite way. It involves action. In this context, Jesus was telling people to prepare themselves—to change whatever needed to be changed—because God’s kingdom (the kingdom of heaven) was approaching.
So how do we prepare to face this heavenly kingdom? How do we make sure we are at peace with this coming King?
Jesus says we need to repent. This implies that we all need to turn from the way we are currently thinking and living. Romans 3:23 explains that “all have sinned and fall short of the glory of God.” Every person reading this sentence has done things that are evil and offensive to this King. Romans later explains that “the wages of sin is death” (Rom. 6:23). Because of our sin, which is an offense to God, we should expect death. But then comes an amazing truth.
“But God shows his love for us in that while we were still sinners, Christ died for us” (Rom. 5:8). The death penalty we should have faced from this King was actually paid for by someone else. The King’s Son, Jesus Christ!1
The Scriptures then say, “If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved” (Rom. 10:9). We are saved by the grace of God through faith in Jesus Christ. It is all about who Jesus is and what He has done. Part of our repentance is to turn from believing that there’s anything we can do to save ourselves—for everything was accomplished by Jesus Christ.
The thought that someone else has paid for our crimes is strange to most of us because it defies our natural way of thinking. And the idea that we need to trust in another person’s sacrifice on our behalf is even more foreign. But understand that while it is strange to us, it is consistent with God’s actions throughout the Scriptures.
We get a picture of this when we read the book of Exodus. In this story, Moses warned Pharaoh repeatedly about what God would do if he did not repent. It climaxed when God said He would bring death to the firstborn of every household if they did not repent. Meanwhile, He told His people that if they put the blood of a lamb over their doorposts, His angel would pass over their homes and not kill the firstborn of that house. So even in the story of the exodus, we see that people had to trust in the blood of a lamb to save them— and this was the only way they could be saved.
