I have never ever been to a snake handling church in my life nor any of the others you listed. I do not support snake handling but, if others do, that is their business between God and them. When I see church services on tv, I really expect people to act like they are glad to be in God’s House. Are you mind reading about the heart rate? I have sensed God’s presence during a very quiet song, sermon, etc. Then, I have sensed His presence during “I’ll Fly Away.” We just have to listen for Him.
