Well, that is understandable since he was in a Pentecostal cult. He needed to get out of that. He obviously did not find the full truth. I don't see how he could not tell if his experience was supernatural or not. Most people know if they are making it up. Does he remember when he received this? How old was he? Can he describe what happened? Was he under pressure to speak in tongues? Was he being coached to make up syllables? This, I think is wrong and is enough to confuse anyone. I have studied scriptures and sought God too, but I come to a different conclusion than your husband. Then again, I was not involved with the cult that he was in. This is so sad. Also, my experience was so real from God that I could not even question that. I did not want to think about it when I was backslid. Wow! how crazy the human mind can work with the help of devils whispering in one's ears.
