2 Nephi 2:27
Wherefore, men are free according to the flesh; and all things are given them which are expedient unto man. And they are free to choose liberty and eternallife, through the great Mediator of all men, or to choose captivity and death, according to the captivity and power of the devil; for he seeketh that all men might be miserable like unto himself.
