Seek the Gifts, that ye be not decieved into following the commandments of men.

"But ye are commanded in all things to ask of God, who giveth liberally; and that which the Spirit testifies unto you even so I would that ye should do in all holiness of heart, walking uprightly before me, considering the end of your salvation, doing all things with prayer and thanksgiving, that ye may not be seduced by evil spirits, or doctrines of devils, or the commandments of men; for some are of men, and others of devils.  Wherefore, beware lest ye are deceived; and that ye may not be deceived seek ye earnestly the best gifts, always remembering for what they are given." (D&C 46:7-8)
