101 Reasons Why I Believe Joseph Smith Was A Prophet
10) 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?
13) And when he had said these words, the Spirit of the Lord was upon him, and he said: Helam, I baptize thee, having authority from the Almighty God, as a testimony that ye have entered into a covenant to serve him until you are dead as to the mortal body....
Thus saith the Lord unto me: A choice seer will I raise up out of the fruit of thy loins; and he shall be esteemed highly among the fruit of thy loins. And unto him will I give commandment that he shall do a work for the fruit of thy loins, his brethren, which shall be of great worth unto them, even to the bringing them to the knowledge of the covenants which I have made with thy fathers. (2 Ne. 3:7, emphasis added.)
The seemingly minor detail unearthed by brother Ricks that the Book of Mormon is apparently the only ancient text that characterizes baptism as a covenant takes on great significance in light of these additional facts. But, it was only the beginning of the knowledge Joseph would bring to the world about God’s sacred covenants, of which we will have occasion to speak more in the future.
