 I personally believe that that is the prayer language that God can give a believer. I believe that's praying in tongues, the prayer language that God is able to give. I don't know how to pray. My English vocabulary runs out. I begin praying in English and then I just say, Lord, I don't know what more to pray. And then I just begin to groan in the spirit and I begin to pray in the language that God has given to me.
