"On the day of Pentecost there were people of many tongues there and once the Holy Ghost arrived, each person spoke in his own tongue and yet was understood by all. Clarity of communication not babble."
Exactly. It existed so that EVERYONE could understand. What's going on now, NOBODY can understand. What occured on Day of Pentecost is diametrically opposed to modern-day speaking in tongues. If someone is babbling some kind of gibberish, it most likely isn't coming from God. (Could it be... SATAN?)
I believe so. Besides being the Father of liars, Satan is also defined as "The author of confusion".
