After King Benjamin's speech, he sent his officials out to ask the people if they believed what he told them.
2 And they all cried with one voice, saying: Yea, we believe all the words which thou hast spoken unto us; and also, we know of their surety and truth, because of the Spirit of the Lord Omnipotent, which has wrought a mighty change in us, or in our hearts, that we have no more disposition to do evil, but to do good continually.
3 And we, ourselves, also, through the infinite goodness of God, and the manifestations of his Spirit, have great views of that which is to come; and were it expedient, we could prophesy of all things.
5 And 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, that we may not bring upon ourselves a never-ending torment, as has been spoken by the angel, that we may not drink out of the cup of the wrath of God.
Everyone cried out together,
Yes, we believe every word that you said. 
6 And now,these are the words which king Benjamin desired of them; and therefore he said unto them: Ye have spoken the words that I desired; and the covenant which ye have made is a righteous covenant.
The king said,
Great, that's what I wanted you to say. 
7 And now, 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.
And he continued his speech, saying,
Now you'll be called the children of Christ.
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.
Under this head you are made free.
There's no other head that can save you.
11 And I would that ye should remember also, that this is the name that I said I should give unto you that never should be blotted out, except it be through transgression; therefore, take heed that ye do not transgress, that the name be not blotted out of your hearts.
12 I say unto you, I would that ye should remember to retain the name written always in your hearts, that ye are not found on the left hand of God, but that ye hear and know the voice by which ye shall be called, and also, the name by which he shall call you.
14 And again, doth a man take an ass which belongeth to his neighbor, and keep him? I say unto you, Nay; he will not even suffer that he shall feed among his flocks, but will drive him away, and cast him out. I say unto you, that even so shall it be among you if ye know not the name by which ye are called.
If you take on the name of Christ, you'll be found at the right hand of God, but if you take any other name, you'll be found on his left hand.
15 Therefore, I would that ye should be steadfast and immovable, always abounding in good works, that Christ, the Lord God Omnipotent, may seal you his, that you may be brought to heaven, that ye may have everlasting salvation and eternal life, through the wisdom, and power, and justice, and mercy of him who created all things, in heaven and in earth, who is God above all. Amen.
