“If the Lord is the shepherd who leads the flock, goodness and mercy are the two sheepdogs that guard the rear of the flock. Goodness and mercy. Not goodness alone, for we are sinners in need of mercy. Not mercy alone, for we are fragile, in need of goodness. We need them both. As one man wrote, ‘Goodness to supply every want. Mercy to forgive every sin. Goodness to provide. Mercy to pardon.’”
Max Lucado, Traveling Light, a commentary on the 23rd Psalm.
