Jesus told the people to follow him because he is the way to God, heaven, and eternal life. When Jesus was on earth, the disciples and others followed him by walking close to him and listening to his words. Today, we follow Jesus by copying his example and by doing what he says.
Then Jesus said to the disciples, "Do you want to be my followers? If you do, you must deny yourselves. You must take up your cross and follow me. For anyone who keeps his life for himself shall lose it. And anyone who loses his life for me shall find it again. What good is it if you gain the whole world and lose eternal life? What could ever be as good as eternal life? (Matthew 16:24-26)
