Mosiah 3

And now it came to pass that when king Benjamin had thus spoken to his people, he sent among them, desiring to know of his people if they believed the words which he had spoken unto them. 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.
