I started watching the video of MacArthur below when I saw the title of the video. I was going to see how long it took him to use Matt. 12 (Luke 11) as one of his arguments against Pentecostals/Charismatics and not realize he's doing exactly what Jesus accused the religious leaders of doing. It only took him a little over 5 minutes. Here are a few quotes from the video, within the first 5 minutes or so:
I am not here to defend the Holy Spirit, he can defend Himself. But I am here to say that the reproaches that are falling on His holy name are falling on me as well. And mostly this comes in the professing church from Pentecostals and Charismatics, who feel they have free license to abuse the Holy Spirit, even blaspheme His holy name. And they do it constantly. How do they do it? By attributing to the Holy Spirit words that He didn't say; deeds that He didn't do; and experiences He didn't produce. Attributing to the Holy Spirit that which is not the work of the Holy Spirit.
Endless human experiences; emotional experiences; bizarre experiences; demonic experiences; are said ti come from the Holy Spirit: visions, revelations, voices from heaven, messages from the Spirit through transcendental means, dreams, speaking in tongues, prophecies, out body experiences, trips to heaven, anointings, miracles...all false, all lies, all deceptions, attributed falsely to the Holy Spirit.
It is a reckless kind of movement, it is a shameful and dangerous sin to heap such abuse on the Holy Spirit.
A way to perceive this would be to see this as a contrast to what we see in Matt. Chapter 12 for example. The leaders of Israel committed the unpardonable sin. And what was that unpardonable sin? It was attributing to satan the work of the Holy Spirit. What is going on today is the opposite: attributing to the Holy Spirit the work of Satan.
He doesn't realize here that what he said thinking it was opposite, is saying exactly the same thing Jesus said. MacArthur is attributing the works of the Holy Spirit to the devil (I'm not saying everything Charismatic/Pentecostal is legit, but there are many legit Holy Spirit works in the things he condemns as being the devil).
Has MacArthur blasphemed the Holy Spirit? He sure seems to have IMO. If so, and it cannot be forgiven, will it keep him out of heaven?
