“If a box is filled with salt it cannot be filled with sand, and if our hearts are filled with hatred of our neighbor, how can God fill them with His love? It is just as simple as that. There can be and there will be no mercy toward us unless we ourselves are merciful. The real test of the Christian then is not how much he loves his friends, but how much he loves his enemies.”  —Ven. Fulton J. Sheen, from his book GO TO HEAVEN
