I left Pentecostal/charismatic churches after 15 years of being in them. I went there as a new Christian, because I didn't know any better. And it seemed exciting!
I left, because I realized 99% of what I was hearing was utter nonsense. Same with the prophecy. Now, I am not saying that God will not use people to speak in tongues or prophecy, but I am saying they are rare gifts today.
I do believe that God can do as he wants. We cannot put him in a box. But I don't think what is happening in Pentecostal and charismatic churches from God. I believe that, because God gave us his Word. Yet only yesterday, I was looking up a church online that some people I met went to, and the focus was on "a new Word!" What happened to the old Word?
God left us his Word and that is what we need to rely on. Not some kind of babbling!
BUT that being said, and I have told this story before, so bear with me. We knew a man, a Fijian East Indian. God called him as an evangelist. He was speaking at a meeting and he said 4 words in an unknown tongue. Just four!
Well, at the end of the meeting, a man came running up from the back with the napkin from the meal in his hand. He was waving it at the evangelist. He said to the evangelist, "Why didn't you say you spoke Armenian?"
Well, of course the evangelist did not speak Armenian. So he showed him the 4 words, and told him them meant, "Jesus Christ is Lord." I don't know how anyone could disagree with that.
So the evangelist was able to lead the man to the Lord. Then, he led 27 members of his family to the Lord. All because God gave him 4 words in Armenian. I saw the napkin, and the words looked real. (I don't speak Armenian, but I trusted this man, who I had known for years, and seen his ministry)
My thought is that we should rely on the Word of God for all things. But if God gives us 4 words to witness to someone and 28 people get saved, we should not scorn that gift.
