"Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. When they saw him, they worshiped him; but some doubted. Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age,”(Matthew 28:16-20 NIV).
Before Jesus, ascended to Heaven, He gave His disciples the Great Commission, His command to make disciples, spreading the Kingdom of Christ to the ends of the earth.
The Greek word here means to travel, depart, take a journey or walk. To go implies aggressive motion, action. We don't sit still and wait for people to come to us. We believe Jesus when he said that the "fields are ready for harvest," so we get out into those fields. As we go, our goal is NOT to convince people we are right, to make converts, or to grow our own local church. Our goal IS: to see people come to Jesus and follow Him with all their hearts and lives forever. We don't try to sugarcoat the Gospel, but declare it boldly.
Jesus called His disciples by telling them to leave everything to follow Him. He called them to be "fishers of men," to live a life of purpose. I like to paint a picture for unbelievers of a new life they can live under the Lordship of Christ. I call non-Christians to radical commitment.
