“I have failed to be an appropriate model for Christian conduct many times. At significant points, when I should have led by example, I failed to embody the very principles I publicly affirm. I have been intolerant, greedy, slothful, and even dishonest. Were someone to say I was an example for how others should live, I would be flattered but would know their assessment was inaccurate. To say Jesus is 'only an example,' as if that were a small thing, underestimates not only the profound difficulty of serving such a role, but also discounts its rarity.”
