He's not even close to doing that.You should be careful as you are dangerously close to Blaspheming the Holy Spirit.
Uh, praying in the Spirit and "speaking in tongues" are quit different. So-called speaking in tongues occurs in public, while praying in the spirit in an unknown tongue is done in private. Or at least should be.Someone who is praying in the spirit in an unknown tongue and you just decide that is of the devil and label the Spirit by which they are operating as such, then you have just called the Holy Spirit the devil, which is exactly what blaspheming the Holy Spirit is.
