Mosiah 18:10-11

“Now I say unto you, if this be the desire of your hearts, what have you against being baptized in the name of the Lord, as a witness before him that ye have entered into a covenant with him, that ye will serve him and keep his commandments, that he may pour out his Spirit more abundantly upon you? And now when the people had heard these words, they clapped their hands for joy, and exclaimed: This is the desire of our hearts.”
