And Jesus came and said to them, “All authority in heaven and on  earth has been given to me. Go therefore and make disciples of all  nations, baptizing them in the name of the Father and of the Son  and of the Holy Spirit, teaching them to observe all that I have  commanded you. And behold, I am with you always, to the end of  the age”. –Matthew 28:19 

As Matthew records it, these were the final words of Jesus to  his disciples. After saying these words, Jesus left this earth to  sit at the right hand of the Father. Jesus had done what he  came to do, and he passed the torch to his disciples. It was  now their responsibility to go out into the world and tell lost  people what Jesus did for them, to make disciples, to baptize,  and to teach people to obey the words of Jesus.
