Here's an interesting article about how seeing people come to desire God's existence is going to be more important in the 21st Century than giving people a bunch of rational reasons to believe in God.
I have to say that I definitely agree with this argument. I've seen a lot of people believe in God without regard to whether every single piece of their belief system matches up rationally. For that matter, I've seen a lot of people believe a lot of other things without regard to rationality. It seems that our culture is moving to an culture that is increasingly centered on emotion rather than rationality. We can complain about this, we can argue that it's not a good move, but I don't think that there's much chance of changing a cultural shift like this. The only way to change a whole culture is to change individuals who can then change the culture.
