"And I would exhort you, my beloved brethren, that ye remember that he is the same yesterday, today, and forever, and that all these gifts of which I have spoken, which are spiritual, never will be done away, even as long as the world shall stand, only according to the unbelief of the children of men.

"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." (Moroni 10: 19, 24-25)
