I don't understand the rational behind shouting and screaming while praying. When I hear people pray for way, I often wonder if our God is deaf or if the loudest prayer gets the fastest answer. How do you reconcile a church situated in a densely populated area putting speakers outside the church to make sure everybody hears their prayers or worse still during their night vigils. Why would you decide to rub people of their good night sleep? It simple means you a very wicked person because that's not love. Your disturbance doesn't guarantee people will troop to your church or does it? I seriously doubt that.
Anyways, back to where I started from, shouting. What's the idea? Letting other people hear your prayers, clapping, jumping and making weird sounds. I'm not talking about praises here, that's totally different. I think the God we all pray to is a quiet and peaceful being and no quite person likes loud conversations. I also think anyone who wants to pray can close their eyes and talk to God. That's what I think.
