this verse ca,e to mind 1 Corinthians 14:2: "For one who speaks in a tongue speaks not to men but to God; for no one understands him, but he utters mysteries in the Spirit" this seems to me to be the praying in toungues I have heard about
When did Tongues, separate? The Tower of Babble
Confusion, God saw why they were building that Tower, it was to climb to heaven and kill God
therefore, later on God came down to earth in Son through the Virgin Mary to represent God Father himself as Son, Jesus as human, revealing God's true Love and mercy for us all to see in miracles of healing. That is done and the Tongues became known, as God can speak any language to anyone to tell them truth over the errors here on earth still.
Look at the day of Pentecost, there were how many people there, and how many different languages spoken then? That others did not understand, yet through the disciples, they heard in their own languages, the truth of Son risen for them to be new in Father, Daddy's, PaPa's Spirit and Truth to love all, not just a few anymore
As Father through risen Son put everyone in one accord, people hearing truth in their own languages, responded in belief or not, as is still happening today, you think?
If I do not understand another persons speaking, then I might begin too ask Daddy, for to hear, or go on in my own accord of flesh nature as I see many have and do that today, myself was included in. that for a while, to see what I needed, taking thinks literally, over Spiritual truth by God for us in risen Son to us to stand in, no matter what, thanks
