For we are accountable for the sin in ourselves, and have to kill it. We are accountable for the good in our neighbor, and have to cherish it. But we are not accountable for the bad in him. He only, in the name and power of God, can kill the bad in himself. We can cherish the good in him by being good to him across all the evil fog that comes between our love and his good.
— George MacDonald, Unspoken Sermons, First Series, “Love Thine Enemy,” quoted in Knowing the Heart of God, p. 347
