“And it came to pass that as my father arose in the morning, and went forth to the tent door, to his great astonishment he beheld upon the ground a round ball of curious workmanship; and it was of fine brass. And within the ball were two spindles; and the one pointed the way whither we should go into the wilderness.
And it came to pass that I, Nephi, beheld the pointers which were in the ball, that they did work according to the faith and diligence and heed which we did give unto them.
And thus we see that by small means the Lord can bring about great things.
For the Lord … said: I will … 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.”
– The Book of Mormon, 1 Nephi 16: 10, 28-29; 17: (12) 13
“And now, my son, I have somewhat to say concerning the thing which our fathers call a ball, or director—or our fathers called it Liahona, which is, being interpreted, a compass; and the Lord prepared it.
…And it did work for them according to their faith in God; therefore, if they had faith to believe that God could cause that those spindles should point the way they should go, behold, it was done; therefore they had this miracle, and also many other miracles wrought by the power of God, day by day.
… For behold, it is as easy to give heed to the word of Christ, which will point to you a straight course to eternal bliss, as it was for our fathers to give heed to this compass, which would point unto them a straight course to the promised land.”
-The Book of Mormon, Alma 37:38, 40, 44
