Now by far the deepest and by far the most personal experience of
every spiritually minded man is his experience of his own inward

thine anger; neither is there any rest in my bones because of my sin.
My loins are filled with a loathsome disease. For, behold, I was
shapen in iniquity." And Daniel, the most blameless of men and a man
greatly beloved in heaven and on earth: "I was left alone and
