Ye Shall Know That It Is By Me That Ye Are Led

1 Nephi 17:13 And I will also be your light in the wilderness; and I will prepare the way before you, if it so be that ye shall keep my commandments; wherefore, inasmuch as ye shall keep my commandments ye shall be led towards the promised land; and ye shall know that it is by me that ye are led.

God doesn't promise a smooth journey.  In fact, God guarantees that there will be a few major bumps in our path. However, at the same time, He promises to sustain and deliver us from all our adversity.   So that, all along the way and in the end, we know that He was with us and that we couldn't have made it without Him.
