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."
Jesus makes 4 points - two actions sandwiched by two statements about Jesus:
1. Jesus has been given all authority in heaven and earth (statement) - Jesus is the King who is in control
2. Go and make disciples of all nations (action) - Why? Because Jesus is the King! We have to spread the news to all nations.
3. Teach them to obey His commands (action) - If Jesus is King and we are telling others that He is King, we need to tell them how to submit to Him or how to live a life for this King.
4. Jesus will be with us to the end of the age (statement) - Jesus promises us something no other prophet, king or ruler can. Jesus' kingship is eternal - He will be our King forever, to the ends of the ages, and His kingship will never perish.
Jesus is the everlasting King, He has authority over heaven and earth. We must spread the news, and tell others that He is King, and that we have to submit to Him and live our lives for Him.
