I would like to know and understand why is it that some preachers today are speaking in tongues. I visit churches and while the preacher is preaching, he or she starts to speak in a language that's unbeknowing to me and probably not just me. Then he/she starts speaking in English again. I was told that the Holy Ghost takes them over then they start that speaking in tongues. Why speak a lanuage in Church during a sermon if no ones know what you are uttering? Please make me understand this. Thank you so much for your reply.
