They Knew Of Christ

They did look forward to the coming of Christ,
considering that the law of Moses
was a type of his coming,
and believing that they must keep
those outward performances until
the time that he should be revealed unto them.

Now they did not suppose that
salvation came by the law of Moses;
but the law of Moses did serve
to strengthen their faith in Christ;
and thus they did retain a hope through faith,
unto eternal salvation.
(Alma 25:15-16)
