Pentecostals speak in "tongues" and sing in "tongues". In new age spirituality there are some who "spirit sing". How many other religions do something similar?
I’ve been baptized in the Holy Spirit and sing in tongues more than any one I know, mostly as prayer in my car or out walking.
One time I spoke to a foreigner in tongues and they carried on a conversation with me. I can only guess that the Holy Spirit had a message for that person.
