~C.S. Lewis, Mere Christianity
GG is God Girl aka Cathleen Falsani) GG: Whos Jesus to you?OBAMA: Right. Jesus is a historical figure for me, and hes also a bridge between God and man, in the Christian faith, and one that I think is powerful precisely because he serves as that means of us reaching something higher. And hes also a wonderful teacher. I think its important for all of us, of whatever faith, to have teachers in the flesh and also teachers in history....
GG: Do you believe in sin?
OBAMA: Yes.
GG: What is sin?
OBAMA: Being out of alignment with my values.
GG: What happens if you have sin in your life?
OBAMA: I think its the same thing as the question about heaven. In the same way that if Im true to myself and my faith that that is its own reward, when Im not true to it, its its own punishment...

Indonesia has the world's largest Muslim population, but Obamas household was not religious. My mother, whose parents were nonpracticing Baptists and Methodists, was one of the most spiritual souls I ever knew, Obama said in a 2007 speech. "But she had a healthy skepticism of religion as an institution. And as a consequence, so did I."
