The weak can never forgive. Forgiveness is the attribute of the strong. (Mahatma Gandhi, 19th-20th century leader of independence in India)

Some people seem to think that if you are a forgiving person, you don’t have much strength of character; you give in too easily, overlooking the fault that was done to you. Gandhi, however, experienced all kinds of opposition and antagonism, but he maintained a forgiving spirit, not out of weakness but from the strength of his convictions and inner courage.

Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you (Colossians 3:13).
