A few times that I've watched Matt Chandler preach, I've noticed that he often (or maybe always) prays with his eyes open. So as he's preparing to pray at the beginning or end of his sermon, rather than shut his eyes he is looking at his congregation as he prays.
This struck me as a bit odd, but I wonder if it should. Does anyone else regularly pray with your eyes open? What do you think of this practice? Are there any biblical statements about shutting our eyes when we pray?
