I visited my niece and her husband in Texas about 15 years ago. Her husbands dad's home. The dad thought he knew me, and invited a man, he knew to the house.
This man is sitting with us at the kitchen table. He says to me, I have heard about you. (hm, I don't know him i thought to myself) He starts talking about a person who heals and etc. ( I thought, dear Holy Ghost, this man is trying me), so I just let him talk. When he was finished is asked, "Hm, where do you think this person is getting power from?" Oh, says the man, the Holy Ghost of course! Wow, I thought to the Holy Ghost, and the Holy Ghost reminded me of what demons hate the most with words. So, I replied, "What about the Powers of the Precious Blood of Christ?"
This man, stood up and roared! at me and said roaring., "What of it!!"
Everyone at the table were silent and shocked. I said to this man, "I did not come for this." I left the kitchen.
My niece came to me and said, "Aunt, you said nothing to make him so angry". I told her, I think I know what happened and I will explain later to you. At 10 pm bedtime I told my niece and her husband what took place in my thoughts and asking the Holy Ghost for assistance. I do believe this man harbors a demon and he heard "Precious Blood of Christ".
If you are excited about powers and those who know(mediums and such) sure you will see powers of Satan. Powers of God, So and Holy Ghost have powers with your sanctifying grace. Which would you rather have, Satan or Gods powers to assist you?
