From the scripture, this point is accurate.
But thank GOD for speaking in tongues as well. Awesome for edification
If P_rehein was right, How would we know when the Spirit is interceding with groaning's.
Lets look at Rom 8: 26, and see what the Greek says.
The meaning of, "Helpeth", is made up of two Greek words and their meanings are, , [1]Stand together with, [2]Against.
So the Holy Spirit stands together with us, Against the problems that is hindering our prayers.
The meaning of, "Infirmities", in this verse, means, "Our inabilities to produce results.
So thank God the Holy Spirit comes to help us, He doesn't do it on Him own, He needs our voice to intercede.
The meaning of, "Maketh intercession with groaning's which cannot be uttered", is, They cannot be spoken in our native tongue, or understood by our minds.
The Holy Spirit helps us pray, So as we pray then pray in tongues, [As we should], The Holy Spirit can take over and use our tongues to intercede for us.
Those of us who have had this experience, Know when the Spirit takes over our tongues, They become different.
Sometimes the Spirit weeps through us, He groans through us, sometimes He gives us a vision of what He is interceding for.
It is when the Holy Spirit is interceding for us, that all things work together for our good, Rom 8: 28.
