When I think about repentance, I am always aware of that parable about the talents found in Matthew 25.  I call it the Parable of the Religious Slave and you will see why in a moment.  Do you remember the story?

The Master gives ten talents to one person and he makes ten talents more.  Well done.  He gives five talents to someone else and she makes five more.  Good job.  But then he gives one talent to the third servant who buries it in the ground and, when the Master returns from his long journey, this third servant gives it back to him.  But the Master is angry.

Why do you think the Master got angry?
