15 Go ye unto all the world, and preach the gospel to every creature Mark 16:15
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. Matthew 28:19-20
11 For it shall come to pass in that day, that every man shall hear the fulness of the gospel in his own tongue, and in his own language, through those who are ordained unto this power, by the administration of the Comforter, shed forth upon them for the revelation of Jesus Christ. Doctrine and Covenants 90:11
