Then the eleven disciples went away into Galilee, to the mountain which Jesus had appointed for them...And Jesus came and spoke to them, saying, "All authority has been given to Me in heaven and on earth. "Go therefore" and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, "teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age." Amen.

Matthew 28:16, 18-20
