False prophets “teach false doctrine; they neither know nor teach the doctrines of salvation. Rather, they have followed cunningly devised fables that they suppose make up the gospel of Christ, and they preach them as such” (McConkie, Millennial Messiah, 71).
Why does Satan use false prophets? (1:16) “Following the Brethren can be more difficult when in some settings wolves are sent among the flock. False prophets will arise, enticing some to follow them, and by their evil works they deceive careless observers into discounting any and all who claim to be prophets. Satan’s order of battle is such that if it is necessary to encourage a hundred false prophets in order to obscure the validity of one true prophet, he will gladly do so” (Maxwell, All These Things Shall Give Thee Experience, 115).
