The bible teaches that God does heal
That's not the Holy Spirit - that's devils manifesting themselves
1 Corinthians 14:2 - For he that speaketh in an unknown tongue speaketh NOT unto men, but unto God: for NO MAN UNDERSTANDS HIM howbeit in the spirit he speaketh mysteries.
Romans 8:26 - Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered in articulate speech.
Be careful, some of what you think is gibberish is actually the work of the Holy Spirit.
Those claiming the work of the Holy Spirit is the work of the devil are in very beep doo and doo
If you want to reference I Cor 14 then you must take into account what the chapter actually says.
Verses 8-9 "For if the trumpet give an uncertain sound, who shall prepare himself to the battle? So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air."
Verses 15-16 "What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest?"
Verses 27-28 "If any man speak in an
unknown tongue,
let it be by two, or at the most
by three, and
that by course; and let one interpret. But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God."
Verse 40 says "Let all things be done decently and in order."
So how exactly do you know what you are saying when speaking in tongues if there is no interpreter?
How do you know whether or not you are blaspheming against God?
Against Jesus on the cross and His teachings.?
Are you actually blaspheming against the Holy Spirit?
It is an unknown tongue that nobody can interpret.
Yet you allow a spirit to possess you to speak things that you have no idea what you are saying...
