"Sin is not to be ignored, nor minimised. It is the most patent fact in life, the darkest experience in the history of the race. It is the root of all the world's tragedies. It is that which makes "conscience a thousand swords," "the torture of an inward hell," "the worm that doth begnaw the soul." (James M. Campbell. The Heart of Gospel: A Popular Exposition of the Atonement. Fleming H. Revell Co. 1907. pg 47.)
