This simply means that there is some good in the worst of us and some evil in the best of us. When we discover this, we are less prone to hate our enemies. When we look beneath the surface, beneath the impulsive evil deed, we see within our enemy-neighbor a measure of goodness and know that the viciousness and evilness of his acts are not quite representative of all that he is. We see him in a new light. We recognize that his hate grows out of fear, pride, ignorance, prejudice, and misunderstanding, but in spite of this, we know God's image is ineffably etched in being. Then we love our enemies by realizing that they are not totally bad and that they are not beyond the reach of God's redemptive love.
