The unpardonable sin is blasphemy against the Holy Spirit. Blasphemy includes ridicule and attributing the works of the Holy Spirit to the devil.
What does God think about attributing works of the devil to the Holy Spirit?
In the church that I just left, the Pastors wife had the whole church (minus me) mesmerized when she told of how she ‘taught’ two young boys how to speak in tongues. I think this is how modern tongues started and continues. In the Bible, no one knew anything about tongues prior to the gift being given by the Holy Spirit. It was ONLY given by the Holy Spirit! Now, it is passed on by peer pressure from HUMANS who think they can push it on their peers and children and the peers think they are missing something if they don’t join in.
I think you would agree that actual languages are spoken in the Bible. Others there understood them. But please explain to me why of the thousands of videos on youtube, there is not ONE SINGLE video of someone speaking an actual known language that someone knows today?
...and who do you think is at work here? Think the guy got the house? Or the other guy got the car? I could send you these videos all day. Think non believers watch this and get brought closer to Christ? Not a chance! And why would God give a ‘gift’ that resulted in turning people from Christ?
