Before I'd finished the series, I ordered The Reason for God by Tim Keller so I could read it. It had been recommended, and though I only knew the title, I ordered it. Interestingly, the back cover says,
"Using literature, philosophy, real life conversations, and potent reasoning, Keller explains how belief in a Christian God is, in fact, a sound and rational one."
I'm interested to read it because Andy Stanley seemed to point out that there are so many questions we cannot answer. The fact is, our faith comes down to our personal experience with God. Our questions do not always disappear---they merely become less important when the undeniable happens to us. When we encounter Jesus, we care less about the unexplainable.
