Unless we are merciful…

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? We must forgive others, for on no other condition will our own sins be forgiven. It is as simple as that. There can be and there will be no mercy toward us unless we ourselves are merciful.
–Blessed Fulton Sheen (1895-1979)
