“Satan Hath Sought to Deceive You”
Doctrine and Covenants 50:2–3
2 Behold, verily I say unto you, that there are many spirits which are false spirits, which have gone forth in the earth, deceiving the world.
3 And also Satan hath sought to deceive you, that he might overthrow you.
President Boyd K. Packer said:
“Be ever on guard lest you be deceived by inspiration from an unworthy source. You can be given false spiritual messages. There are counterfeit spirits just as there are counterfeit angels [see Moroni 7:17]. . . .
“The spiritual part of us and the emotional part of us are so closely linked that [it] is possible to mistake an emotional impulse for something spiritual. We occasionally find people who receive what they assume to be spiritual promptings from God, when those promptings are either centered in the emotions or are from the adversary.”
