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.

and ye shall know that it is by me that ye are led.
