Wherefore ye may know with a perfect knowledge, it is of God; but whatsoever thing persuadeth men to do evil, and believe not in Christ, and deny him, and serve not God, then ye may know with a perfect knowledge it is of the devil,
For after this manner doth the devil work, for he persuadeth no man to do good, no not one; neither doth his angels; neither do they who subject themselves unto him.
And now, my brethren, seeing that ye know the light by which ye may judge, which light is the light of Christ, see that ye do not judge wrongfully; for with that same judgment which ye judge, ye shall also be judged.
Wherefore I beseech you, brethren,
that ye should search diligently in the light of Christ, that ye may know
good from evil; and if ye will lay hold upon every good thing, and condemn
it not, ye certainly will be a child of Christ.
Moroni 7:14..18, RLDS Book of Mormon
