Remorse vs Repentance

.... from the book: Pardon and Peace. "Sorrow for sin has two aspects, two slants as it were, one backwards and one forward. Looking back, the penitent regrets and detests sin; looking forward, he determines to avoid it. Determination to avoid both sin and its occasions, in other words, firm purpose of amendment, is the crucial test of the reality of contrition. He who is determined to do his best to avoid sin, undoubtedly has true repentance, even though he feels spiritually dry as a desert and indevout as an iceberg. The proof of contrition is in the effective will to reform. It is all-important that there should be no misunderstanding about the true meaning of contrition; remorse must on no account be confused with repentance." (intro Chpt 13)
