And he said unto them, Go ye into all the world, and preach the gospel to every creature.

Matthew 28:19-20
19  Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20  Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world.

Amen.
