Themis, I think that many in the church have never had a true experience from the Holy Ghost, and so when they get a good feeling, then they assume that it is from the Holy Ghost.
How do you tell the difference?
I think that that is probably what happened some in the "Dunn" case.
Except in the Dunn case it wasn't a one off, it was worldwide, over a period of decades, with whole congregations experiencing it at the same time.
Having said that, there are legitimate experiences of the Holy Ghost bearing testimony, and it is unmistakeably scriptural.
How can you tell it is legitimate?
But, for someone who has had the experience to try to explain it to someone who has not, is like someone trying to tell someone else who has never flown what it is like.
Then how can Missionaries explain to investigators what they should experience if, when they take Moroni's challenge the Holy Spirit testifies to them of it's truthfulness?
I have a suggestion for you and Drifting. Why don't you two, just for a few days, try to stop looking for ways to argue and try to really take Moroni's challenge seriously!
Been there and done that.
You just choose not to believe what the Holy Spirit told me because it doesn't agree with what you want to believe...
