First rumors turn to partial truths. Partial truths become hearsay, murmurings among the people, and maybe even occasional "leaks" among the masses. But with the truth of all things false ideas and secret works are continued to be exposed. As the Lord said
"And the rebellious shall be pierced with much sorrow; for their iniquities shall be spoken upon the housetops, and their secret acts shall be revealed." (D&C 1:3)Eventually as the whispers and chatter get louder, They become truths clearly exposed. Where they can no longer be hidden. Or the false ideas are proven to be false.
"And the day cometh that the words of the book which were sealed shall be read upon the house tops;" (2 Nep 27: 11)
"Therefore, whatsoever you have spoken in darkness shall be heard in the light, and that which you have spoken in the ear, in closets, shall be proclaimed upon the housetops." (Luke 12:3, OT Luke 8:18)
I am always amazed how naturally the Lord works in his patterns and it seems these patterns fit exactly how he had already foretold it would happen only now being in hindsight can they begun to be seen.
