Alma 34

Atonement must be made, otherwise we must all perish.

Testimony of the 3 Witnesses

Be it known to everyone we've seen the plates of this record by the grace of God. It's a record of Nephites, Lamanites and Jaredites and was translated by gift/power of God and his voice has declared it to us.

Angel showed us the writings and by the grace of God we know these things are true.

It is marvelous to us, and God commanded that we bear record it's true.

If we're faithful we'll rid our garments of the sin of all men and glory be to the Father, Son and the Holy Ghost.
