The world does not consist of 100 percent Christians and 100 percent non-Christians. There are people (a great many of them) who are slowly ceasing to be Christians but who still call themselves by that name: some of them are clergymen. There are other people who are slowly becoming Christians though they do not yet call themselves so.
C. S. LewisWe have a strange illusion that mere time cancels sin. I have heard others, and I have heard myself, recounting cruelties and falsehoods committed in boyhood as if they were no concern of the present speaker's, and even with laughter. 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: if we have repented these early sins we should remember the price of our forgiveness and be humble.
