Really?
People need more discernment and to validate what they are experiencing through and based on Scripture, not some kind of emotional experience.
2 Corinthians 11:13-15 For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ. And no wonder, for even Satan disguises himself as an angel of light. So it is no surprise if his servants, also, disguise themselves as servants of righteousness. Their end will correspond to their deeds.
There is a real danger of deception in the church when people simply accept at face value anything that anyone says is from God or by God.
"I have a word from the Lord...." is all some people need to hear to completely throw caution to the wind and accept anything some self-proclaimed prophet has to say. They swallow the whole thing without questioning because they don't want to be found fighting God and don't even stop to consider that the prince of the power of the air, can do wonders and signs.
I don't doubt your friend experienced something.
I DO doubt it was from God.
No, no, NO!!!
You GOTTA shake their hand!!
Doctrine and Covenants Section 129
13, There are both resurrected and spirit bodies in heaven; 49, Keys are given whereby messengers from beyond the veil may be identified.
1 There are two kinds of beings in heaven, namely: Angels, who are resurrected personages, having bodies of flesh and bones;
2 For instance, Jesus said: Handle me and see, for a spirit hath not flesh and bones, as ye see me have.
3 Secondly: the spirits of just men made perfect, they who are not resurrected, but inherit the same glory.
4 When a messenger comes saying he has a message from God, offer him your hand and request him to shake hands with you.
5 If he be an angel he will do so, and you will feel his hand.
6 If he be the spirit of a just man made perfect he will come in his glory; for that is the only way he can appear;
7 Ask him to shake hands with you, but he will not move, because it is contrary to the order of heaven for a just man to deceive; but he will still deliver his message.
8 If it be the devil as an angel of light, when you ask him to shake hands he will offer you his hand, and you will not feel anything; you may therefore detect him.
9 These are three grand keys whereby you may know whether any administration is from God.
Joseph Smith
