Some people say it's demonic but I lived for the devil for 31 years and I never spoken those gibberish tongues as they say, but not too long after I was born again gloriously radically saved, I received the baptism of the holy spirit with the evidence of speaking in tongues in my bedroom while waiting on the Lord spending time with him and I had not even been saved one year, I know people have been saved for 30 to 40 years and they don't have the time of the day to spend time with the Lord, shame on them.
