The seemingly strong person can only boomerang his assailant's weapon back onto the assailant himself. It is precisely the strong person who can forgive. A cruel way of ridding oneself of nuisance animal is to put ground glass in the animal's food. As the animal eats, it swallows tiny fragments of sharp glass. The needle-sharp fragments perforate the animal's digestive tract and the animal haemorrhages to death in terrible pain.
Most people look upon the matter of forgiving assailants as no more than eating ground glass.
People who think like this, of course, have it all wrong. This is the ground glass diet of those who mistake forgiveness for wimpiness. Five hundred years after Joseph a prophet appeared, Jeremiah by name, who was mistreated much as Joseph had been. The Lord is my portion. To have as our portion that Lord whose faithfulness to us is great is to be steeped in his ceaseless mercies.
