I read this quote by Dietrich Bonhoeffer today:

“The only way to overcome evil is to let it run itself to a standstill because it does not find the resistance it is looking for. Resistance merely creates further evil and adds fuel to the flame. But when evil meets no opposition and encounters no obstacle but only patient endurance, its sting is drawn, and at last it meets an opponent which is more than its match.” The Cost of Discipleship, p. 157-158.

I wonder how many wars, personal and political, could have been prevented by this simple advice.
