Nephi had no idea how he was going to get the plates. He just knew that the Lord would help him accomplish the thing which He had commanded. This is true faith – to put your total trust in the Lord.

"More than ever before, I understand what the ancient prophet Nephi felt when he had been given the seemingly insurmountable task by his father, Lehi, to gain possession of the brass plates…I must go on many occasions, as did Nephi of old, being 'led by the Spirit, not knowing beforehand the things which I should do.' Yes, though the night be dark, 'I do not ask to see the distant scene—one step [is] enough for me.'" (Conference Report, Apr. 1970, pp.125-126 as taken from Latter-day Commentary on the Book of Mormon compiled by K. Douglas Bassett, p. 16)

"Walk to the edge of the light, and perhaps a few steps into the darkness, and you will find that the light will appear and move ahead of you." (Lucille C. Tate, Boyd K. Packer: A Watchman on the Tower, p.138)
