Moses 5

 Even though there were much wickedness and secret combinations taught by Satan as the children of men grew, we also learn - 

"...the Gospel began to be preached, from the beginning, being declared by holy angels sent forth from the presence of God, and by his own voice, and by the gift of the Holy Ghost.

59 And thus all things were confirmed unto Adam, by an holy ordinance, and the Gospel preached, and a decree sent forth, that it should be in the world, until the end thereof; and thus it was.,,"  Moses 5:58-59
