The abundance of a grateful heart gives honor to God even if it does not turn to Him in words. An unbeliever who is filled with thanks for his very being has ceased to be an unbeliever.
Paul TillichOut of the element of participation follows the certainty of faith; out of the element of separation follows the doubt in faith. And each is essential for the nature of faith. Sometimes certainty conquers doubt, but it cannot eliminate doubt. The conquered of today may become the conqueror of tomorrow. Sometimes doubt conquers faith, but it still contains faith. Otherwise it would be indifference.

Paul TillichForgiving presupposes remembering. And it creates a forgetting not in the natural way we forget yesterday's weather, but in the way of the great "in spite of" that says: I forget although I remember. Without this kind of forgetting no human relationship can endure healthily. I don't refer to a solemn act of asking for and offering forgiveness. Such rituals as sometimes occur between parents and children, or friends, or man and wife, are often acts of moral arrogance on the one part and enforced humiliation on the other. But I speak of the lasting willingness to accept him who has hurt us.
