“We have a strange illusion that mere time cancels sin. I have heard others, and I have heard myself, recounting cruelties and falsehoods committed in boy-hood as if they were no concern of the present speaker’s, and even with laugh-ter. But mere time does nothing either to the fact or to the guilt of a sin. The guilt is washed out not by time but by repentance and the blood of Christ.”

“. . . evil can never be undone, but only purged and redeemed.” Dorothy L. Sayers: The Emperor Constantine: A Chronicle.

“Faith is no more than the Word warrants, then the blood of atonement en-courages, than the promise of God deserves.” Charles H. Spurgeon.

“Through all his tragedies and triumphs, the spiritual dimension is never absent from David’s life. When he sins, he recognizes it as sin against God (Ps. 51). When he triumphs, he turns in praise to the God who has given him the vic-tory (Ps. 18). All of this bespeaks of a man for whom all of life is God’s.” Leland Ryken: Words of Delight, 136.
