2 Nephi 27:11

And the day cometh that the words of the book which were sealed, shall be read upon the house-tops; and they shall be read by the power of Christ: and all things shall be revealed unto the children of men which ever hath been among the children of men, and which ever will be, even unto the end of the earth.

The day will come when the sealed words of the book will be read from the rooftops. They will be read by the power of Christ. All things will be shown to people. This includes everything that has ever been and everything that will ever be until the end of the earth.

The day is coming when the sealed words will be shouted from the rooftops. They’ll be proclaimed by the power of Christ, and everything that has ever happened or ever will happen—right to the end of the earth—will be revealed to humanity.
