Why is faith a virtue?
If you ask a believer to focus on God in prayer, the part of their brain responsible for attention and concentration becomes very active. If you ask an atheist to do the same, the characteristic patterns of prayer don’t appear because there’s nothing for the atheist to focus on. Science tells us that the way humans understand God is more a feeling and experience than an idea or set of beliefs. For atheists, the pattern of connections across the brain that create this experience aren’t there. There is no God in their brains. It turns out that some belief in God is vital for people to experience and know God. In some measurable way, you have to leap before you look.
That seems foolish to many people, and I’m one of them. The Bible constantly extolls the virtues of faith and belief in things unseen. I think that reflects an intuitive understanding of what we’ve learned about the neurology of belief in modern times. Many of best things about Christianity only happen after you know God, but God can’t be proven. That’s why faith is extolled as such a virtue.
