Mosiah 3 - 6

As King Benjamin ended his speaking of the words that were delivered to him by an angel, he beheld that his people had -

"...fallen to the earth, for the fear of the Lord had come upon them.
2 And they had viewed themselves in their own carnal state, even less than the dust of the earth." (Book of Mormon Mosiah 4:1 - 2)

And in doing so -

"...they all cried aloud with one voice, saying: O have mercy, and apply the atoning blood of Christ that we may receive forgiveness of our sins, and our hearts may be purified; for we believe in Jesus Christ, the Son of God, who created heaven and earth, and all things; who shall come down among the children of men." (Book of Mormon Mosiah 4:2)

And as they did -

"...the Spirit of the Lord came upon them, and they were filled with joy, having received a remission of their sins, and having peace of conscience, because of the exceeding faith which they had in Jesus Christ who should come..." (Book of Mormon Mosiah 4:3)

Witnessing this, King Benjamin continues -

"...if ye have come to a knowledge of the goodness of God, and his matchless power, and his wisdom, and his patience, and his long-suffering towards the children of men; and also, the atonement which has been prepared from the foundation of the world, that thereby salvation might come to him that should put his trust in the Lord, and should be diligent in keeping his commandments, and continue in the faith even unto the end of his life, I mean the life of the mortal body—
7 I say, that this is the man who receiveth salvation, through the atonement which was prepared from the foundation of the world for all mankind...And this is the means whereby salvation cometh. And there is none other salvation save this which hath been spoken of; neither are there any conditions whereby man can be saved except the conditions which I have told you."" (Book of Mormon Mosiah 4:6 - 8)

And these are the conditions -

Believe in God; believe that he is, and that he created all things, both in heaven and in earth; believe that he has all wisdom, and all power, both in heaven and in earth; believe that man doth not comprehend all the things which the Lord can comprehend.
10 And again, believe that ye must repent of your sins and forsake them, and humble yourselves before God; and ask in sincerity of heart that he would forgive you... even so I would that ye should remember, and always retain in remembrance, the greatness of God, and your own nothingness, and his goodness and long-suffering towards you, unworthy creatures, and humble yourselves even in the depths of humility, calling on the name of the Lord daily, and standing steadfastly in the faith of that which is to come, which was spoken by the mouth of the angel." (Book of Mormon Mosiah 4:9 - 11)

And then King Benjamin promises that -

"...if ye do this ye shall always rejoice, and be filled with the love of God, and always retain a remission of your sins; and ye shall grow in the knowledge of the glory of him that created you, or in the knowledge of that which is just and true." (Book of Mormon Mosiah 4:12)

The people were so filled with the Spirit that they responded -

"...we are willing to enter into a covenant with our God to do his will, and to be obedient to his commandments in all things that he shall command us, all the remainder of our days..." (Book of Mormon Mosiah 5:5)

To which King Benjamin happily tells them -

"...because of the covenant which ye have made ye shall be called the children of Christ, his sons, and his daughters; for behold, this day he hath spiritually begotten you; for ye say that your hearts are changed through faith on his name; therefore, ye are born of him and have become his sons and his daughters.
8 And under this head ye are made free, and there is no other head whereby ye can be made free. There is no other name given whereby salvation cometh; therefore, I would that ye should take upon you the name of Christ, all you that have entered into the covenant with God that ye should be obedient unto the end of your lives.
9 And it shall come to pass that whosoever doeth this shall be found at the right hand of God, for he shall know the name by which he is called; for he shall be called by the name of Christ." (Book of Mormon Mosiah 5:7 - 9)

Can their be anything greater than to become a child of Christ?
