I accepted Jesus into my heart and attended Assembly of God in Pratt Kansas, speaking in tongues, (glossolalia) every Sunday for years. I never did it myself; however, I had begun practicing at home and I honestly believe I would have started within a few months if I had not decided to become a preacher.
Each Sunday, it is the same people doing the speaking. They ramble on for a few minutes and then the church would fall silent as everyone waited for someone else to be blessed with the interpretation. It went on like this Sunday after Sunday.
People spoke in tongues when the Holy Ghost moved them to do so. It was always during a passionate sermon and just before the collection plate was passed. Anyone can do it, it just takes a little practice. The rewards you get are the awe, respect, and admiration of the congregation. It’s a bit like a good witnessing story. Do it right and everyone pats you on the back. If you break down and cry after doing it your first time and claim you don’t know what happened, the accolades will elevate you to HOLY status.
