You are probably aware that Corrie ten Boom, along with her sister and father, were sent to Ravensbruck, a Nazi concentration camp, for hiding Jews.
Her sister and father died there, but Corrie was released, due to a “clerical error.” And the Kingdom of God is better off for it.
Corrie ten Boom likened forgiveness to letting go of a bell rope. If you have ever seen a country church with a bell in the steeple, you will remember that to get the bell ringing you have to tug awhile. Once it has begun to ring, you merely maintain the momentum. As long as you keep pulling, the bell keeps ringing.
Corrie ten Boom says forgiveness is letting go of the rope. It is just that simple, but when you do so, the bell keeps ringing. Momentum is still at work. However, if you keep your hands off the rope, the bell will begin to slow and eventually stop.
It is like that with forgiveness. When you decide to forgive, the old feelings of unforgiveness may continue to assert themselves. After all, they have lots of momentum. But if you affirm your decision to forgive, that unforgiving spirit will begin to slow and will eventually be still. Forgiveness is letting go of the "rope" of retribution.
