Make disciples of all nations

18And Jesus came and said to them, "All authority in heaven and on earth has been given to me. 19 Go therefore and make disciples of all nations, baptizing them in[a] the name of the Father and of the Son and of the Holy Spirit

This verse is the mission of all Christians.  Christ says here I am, I have died for your sins and now I stand before you alive; go out and tell the world.  If we believe that He is who He says He is, then we have no choice but to tell the world.  If Christ really did come and die for the sins of the world and stands at the door and knocks, then it becomes our job to tell the world His message.  If we believe that we all have an appointed time to die and face judgement, then how selfish would we be to not tell everyone who surrounds us, and to give our lives to this one great mission
