Faith in Christ
Yea, and how is it that ye have forgotten that the Lord is able to do all things according to his will, for the children of men, if it so be that they exercise faith in him? Wherefore, let us be faithful to him. 1 Nephi 7:12–13
Nephi teaches his brothers that the Lord works mighty things for those who exercise faith in Him. It is an early statement of the first principle, faith in the Lord.
How we know: Jehovah is the premortal Christ (Abraham 1:16; D&C 110:3–4)
