This one really, really hits home:
"Our fathers were our models for God. If our fathers bailed, what does that tell you about God?"
Other favorites, reminiscent of my personal favorite quote:
"It's only after we've lost everything that we're free to do anything."
"Only after disaster can we be resurrected."
This one keeps me awake at night:
"This is your life and it's ending one minute at a time."
