If the cross shows me that I am far worse than I had ever imagined, it also shows me that my evil has been absorbed and forgiven. If the worst thing any human can do is kill God's son, and that can be forgiven, then how can anything else not be forgiven?
I have a reverence for medicine because I hero-worshiped my father [a former doctor], and because I admire doctors, I admire study, empiricism and rational thought. I don't study, empiricize or think rationally myself - but I admire it in others.
