2 Nephi 30:18

Wherefore, all things which have been revealed unto the children of men, shall at that day be revealed; and Satan shall have power over the hearts of the children of men no more, for a long time. And now, my beloved brethren, I must make an end of my sayings.

So, all things that have been shown to people will be shown at that day. Satan will have no power over people’s hearts for a long time. And my dear brothers, I must end what I am saying.

Everything that’s ever been revealed to people will be made known on that day. Satan will have no power over people’s hearts—at least not for a long time. Now, my friends, I have to end my message here.
