Speaking in tongues is utter nonsense word salad any way you chop it.

Could someone please tell me why in the world it is necessary for God to deliberately confuse our faculties?

Through our faculties, God gave us the ability to survive, learn, to think about ourselves and the environment he provided us. The reason we have and continue to exist is because our sight, smell, taste, touch, hearing allow us to get information and interact with his creation.

He set all this up and we get to experience life as individuals with the capacity to think of ourselves, of our plight, for good or bad - but language wouldn't be a thing, nor writing, running water, medicine, nor anything requiring formal logic or a scientific method in any capacity had he not given us some method to learn!

Then he says to ignore our faculties, to believe in something we cant prove less our souls be damned.

and how does one apply logic to justify any part of a system that requires you to disregard logic first and foremost!??

No hate at all, honestly, searching for answers really
