Moroni testifies that good only comes into the world through the power and gifts of God. Those who reject the Spirit and gifts of God in this life will die in their sins.
“…And now I speak unto all the ends of the earth—that if the day cometh that the power and gifts of God shall be done away among you, it shall be because of unbelief. And wo be unto the children of men if this be the case; for there shall be none that doeth good among you, no not one. For if there be one among you that doeth good, he shall work by the power and gifts of God. And wo unto them who shall do these things away and die, for they die in their sins, and they cannot be saved in the kingdom of God; and I speak it according to the words of Christ; and I lie not. And I exhort you to remember these things; for the time speedily cometh that ye shall know that I lie not, for ye shall see me at the bar of God; and the Lord God will say unto you: Did I not declare my words unto you, which were written by this man, like as one crying from the dead, yea even as one speaking out of the dust?” (Moroni 10:24-27)
“I declare these things unto the fulfilling of the prophecies. And behold, they shall proceed forth out of the mouth of the everlasting God; and his word shall hiss forth from generation to generation. And God shall show unto you, that that which I have written is true.” (Moroni 10:28-29)
-Do many work by the power and gifts of God without knowing it?
-Are there ordinances and covenants that can endow a person with greater strength to work by the power and gifts of God (if the person is true and faithful to the covenants made with God)?
