Have you been called to go out on a limb for God? You can bet it won't be easy. Limb-climbing has never been easy. Ask Joseph. Or, better yet, ask Jesus. He knows better than anyone the cost of hanging on a tree.

Very, very rarely will I leave San Antonio to speak somewhere else. I used to do that, and it just about wore me out, so I quit traveling.

I work in theology and Christian books all day long, when Im studying, so its just kind of nice to pick up something different. The books that have influenced me, theres not just one book that was a watershed, although Mere Christianity was as much as any.

I think the one thing that I cannot do without each day is hope. If you put me in a position where you took all my hope away, I'm not sure I could make it through the day.

Has worrying about tomorrow every changed it?

It deeply concerns me that somebody who knows little or nothing about the Christian faith would hear Mr. Trump call himself a Christian and then make a decision based on the Christian faith, based on his behavior.

When God is all you have, then all you have, is all you need.
