Repentance has great power.
It takes the charcoal and makes it a diamond. It takes the wolf and makes it lamb.
It takes the savage and makes him a saint.
It takes the bloodstained bandit and makes him the first inhabitant of heaven.
Precisely, because repentance has such power, that is why the devil struggles to prevent man from repentance. This explains the objections of many people to repentance and confession.
