Leaving it empty, doesn't look good at all. Besides, it looks like as if, they are keeping their distance from the presence of God.
It's like watching a concert, where everyone else would of course get as close as possible to their idol. Would there be anyone saying, "I love him/her, but well, I guess just seeing it from here is good enough."?

Let us learn to love the presence of God. Isn't the purpose for going to church is seeking the presence of God, and not just fulfilling a religious duty?
