If Thou Wilt Bow Down Before God – Alma 22:15-16

15 And it came to pass that after Aaron had expounded these things unto him, the king said: What shall I do that I may have this eternal life of which thou hast spoken? Yea, what shall I do that I may be born of God, having this wicked spirit rooted out of my breast, and receive his Spirit, that I may be filled with joy, that I may not be cast off at the last day? Behold, said he, I will give up all that I possess, yea, I will forsake my kingdom, that I may receive this great joy.
16 But Aaron said unto him: If thou desirest this thing, if thou wilt bow down before God, yea, if thou wilt repent of all thy sins, and will bow down before God, and call on his name in faith, believing that ye shall receive, then shalt thou receive the hope which thou desirest.
(Alma 22:15-16)

After hearing Aaron teach the gospel, the king of the Lamanites was highly motivated to act. He felt that he needed a change of heart, or as he put it, to have “this wicked spirit rooted out of my breast.” He knew that, by the power of God, he could not only receive eternal life in the world to come, but could also be “filled with joy” in this life. He could also avoid being “cast off at the last day.” He had an eternal perspective. He was keenly aware that he needed divine help. He was prepared to receive the blessings of the Atonement of Jesus Christ. He only needed one thing: a set of specific instructions. He had the desire, but he needed to know what to do.
Aaron instructed the king to do the following:

1. Bow down before God. 
2. Repent of all thy sins. 
3. Call on His name in faith. 
4. Believe that you will receive what you are asking for.
