Faith in Him

“And now, I, Moroni would speaksomewhatconcerning these things; I would show unto the world that faith is things which are hoped for and not seen; wherefore, dispute not because ye seenot, for ye recieve no witness until after the trial of your faith.
For it was by Faith that Christ showed himself unto our fathers after he had risen from the dead; and he showed not himself unto them until after they had fiath in him; wherefore, it must needs be that some had faith in hime, for he showed himself not unto the world.”
