The Great Commission
Matthew 28:18-20 KJV
And Jesus came and spake unto them, saying, All power is given unto me in heaven an in earth.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and the Son, and of the Holy Ghost:
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.
