The Doctrine and Covenants

Doctrine and Covenants, Section 22

BEHOLD, I say unto you that all old covenants have I caused to be done away in this thing; and this is a new and an everlasting covenant, even that which was from the beginning. Wherefore, although a man should be baptized an hundred times it availeth him nothing, for you cannot enter in at the strait gate by the law of Moses, neither by your dead works. For it is because of your dead works that I have caused this last covenant and this church to be built up unto me, even as in days of old. Wherefore, enter ye in at the gate, as I have commanded, and seek not to counsel your God. Amen.
