George Albert Smith taught,

“The Lord has a way of accomplishing things that we are unable to do, and never asks us to do anything that he does not make the way possible. That is what he told us through Nephi. He will not require anything without preparing the way.

“’And it came to pass that I, Nephi, said unto my father: I will go and do the things which the Lord hath commanded, for I know that the Lord giveth no commandments unto the children of men, save he shall prepare a way for them that they may accomplish the thing which he commandeth them.’ [1 Nephi 3:7.]

“If you have something that the Lord asks or expects you to do and you don’t know just how to proceed, do your best. Move in the direction that you ought to go; trust the Lord, give him a chance, and he will never fail you.”
