One excerpt from his book (written with his daughter):
We know all too well the cruelties, hurts, and hatreds that poison life on our planet. But my daughter and I have come together to write this book because we know that the catalogue of injuries that we can and do inflict on one another is not the whole story of humanity, not by a long measure — as I hope you will see and as you no doubt know in your heart. We are indeed made for something more. We are made for goodness.Amen!
