Experiment is the mother of knowledge.

If we don't pray according to the needs of the heart, we repress our deepest longings. Our prayers may not be rational, and we may be quite aware of that, but if we repress our needs, then those unsaid prayers will fester.

A book comes and says, 'Write me.' My job is to try to serve it to the best of my ability, which is never good enough, but all I can do is listen to it, do what it tells me and collaborate.

To pray is to listen, to move through my own chattering to God, to that place where I can be silent and listen to what God may have to say.

There is nothing so secular that it cannot be sacred, and that is one of the deepest messages of the Incarnation.

If I have something I want to say that is too difficult for adults to swallow, then I will write it in a book for children.

When I start a new seminar I tell my students that I will undoubtedly contradict myself, and that I will mean both things. But an acceptance of contradiction is no excuse for fuzzy thinking. We do have to use our minds as far as they will take us, yet acknowledge that they cannot take use all the way.
