How can we tell the difference between God’s influence and other things like emotion?
What are signs of good versus evil spiritual energy?
What are signs of demonic influence?
We discuss these and other questions in this presentation; slides here:
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.
And also Satan hath sought to deceive you, that he might overthrow you.
Behold, I, the Lord, have looked upon you, and have seen abominations in the church that profess my name.
Behold, verily I say unto you, there are hypocrites among you, who have deceived some, which has given the adversary power; but behold such shall be reclaimed; (D&C 50)
Nothing is a greater injury to the children of men than to be under the influence of a false spirit when they think they have the Spirit of God (Joseph Smith)
How can I tell when my thoughts and feelings are my own, or revelation from God? How can I tell if an emotionally-satisfying narrative or activity is good for my soul, or would lead me away from God?
The answer to both questions is discernment.
