As I was thinking about what to include in this blog today, I figured I would copy what someone else said [with hopes that you would find it as sufficient as I did].
18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 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.
15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
21 Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you.
8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
