And after they have been scattered, until they shall
be persuaded to believe in Christ, the Son of God,
and the atonement, which is infinite for all mankind—
and when that day shall come that they shall
believe in Christ, and worship the Father in his name,
with pure hearts and clean hands,
and look not forward any more for another Messiah,
then, at that time, the day will come that
it must needs be expedient that
they should believe these things.
(2 Nephi 25:16)
