Forgiven people forgive. Most of us most of the time say we are forgiving but when we are seriously hurt it is so much harder. Resentment can resurface when there is a drip drip effect. Most of us have someone we struggle to forgive. This passage shows how we should guard against this. Peter thought that by saying we should forgive 7 times that he was excelling in his fervour but Jesus demonstrates that the Christian life involves limitless forgiveness. He knows that this will be hard for us.
