No motive, even that of affection for anyone, can justify the doing of evil. But to help someone in need, a good work may sometimes be left, or a better undertaken in its place. For in so doing, the good work is not lost, but changed for what is better. Without love, the outward work is of no value; but whatever is done out of love, be it never so little, is wholly fruitful. For God regards the greatness of the love that prompts a man, rather than the greatness of his achievement.
Whoever loves much, does much. Whoever does a thing well, does much. And he does well, who serves the community before his own interests.
thomas a kempis, the imitation of CHRIST, chapter 15.
