Alma 22:11 - 22:15
Alma 22:11 And he said: Yea, I believe that the Great Spirit created all things, and I desire that ye should tell me concerning all these things, and I will believe thy words.
The king tells Aaron that he believes that the Great Spirit did create all things but he want to learn more about it. He will believe whatever Aaron teaches him as well.
Alma 22:12 And it came to pass that when Aaron saw that the king would believe his words, he began from the creation of Adam, reading the scriptures unto the king—how God created man after his own image, and that God gave him commandments, and that because of transgression, man had fallen.
Aaron, I comply with the king's requests opens his scriptures and begin with the creation story and Adam and Eve. He recounts the fall of Adam that was in consequence of breaking of commandments and as a result, Adam and Eve become mortal beings.
Alma 22:13 And Aaron did expound unto him the scriptures from the creation of Adam, laying the fall of man before him, and their carnal state and also the plan of redemption, which was prepared from the foundation of the world, through Christ, for all whosoever would believe on his name.
Aaron went into greater detail concerning the fall of Adam and Eve. Hr told the king that they had become under the influence of sin and corruption, but that a plan was in place so they could, as well as ourselves, could now return to God's presence. This plan centered on Christ and that it was put in place even before the world was created. To begin the process to take advantage of this plan of redemption was believe on the name of Christ.
Alma 22:14 And since man had fallen he could not merit anything of himself; but the sufferings and death of Christ atone for their sins, through faith and repentance, and so forth; and that he breaketh the bands of death, that the grave shall have no victory, and that the sting of death should be swallowed up in the hopes of glory; and Aaron did expound all these things unto the king.
Aaron said that the purpose of the plan of redemption was to save men from their fallen state because they could not do it themselves. A Savior was needed to suffer the judgment that was do to anyone who committed sins. And because someone was set up to pay this price, mankind could now be saved by having faith in the ability of Christ to save us and repent of their sins. If men would do this then death would not keep us from returning to God's presence and we could have hope that one day things would be better then what we have to endure in this mortal state.
Alma 22:15 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.
The king now asks how can he take advantage of this plan of redemption that Aaron has told him about. He wants to know how he can ride himself of the desire to commit sin and now be filled instead the desire to do good so he can be filled with the joy that comes with living a sinless life. He wants to be able to enter God's kingdom when the time comes and he is willing to give up all his possessions in order to obtain this great benefit.
Are any of us will to give up all we have to obtain eternal life? We can only answer this ourselves, but it is an honest assessment on our part as to our dedication to living the gospel completely.
