Matthew 28:16-20 - The Great Commission
16 The eleven disciples went into Galilee to the mountain where Jesus specified. 17 When they saw him, they bowed down in adoration for him. But some doubted (were lacking faith). 18 Jesus came to them and spoke to them, saying: All authority has been given to me in heaven and on earth. 19 Go and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit. 20 Teach them to observe all the things I have commanded you. Behold, I am with you always, even to the end of the age.
