This room was a sacred space, a place that he had chosen to make especially his own, a place redeemed from mere "use" in which he would make a conscious attempt to be at rest and to put a part of his life in order. In short, this was the evidence that the man was able to pray.
When somebody you've wronged forgives you, you're spared the dull and self-diminishing throb of a guilty conscience. When you forgive somebody who has wronged you, you're spared the dismal corrosion of bitterness and wounded pride. For both parties, forgiveness means the freedom again to be at peace inside their own skins and to be glad in each others' presence.
