Light shines in the darkness for the upright, the psalmist sings.
Isaiah declares that when we loose the bonds of injustice and
share our bread with the hungry, the light breaks forth like the
dawn. In another passage from the Sermon on the Mount,
Jesus, the light of the world, calls his followers to let the light
of their good works shine before others. Through baptism we
are sent into the world to shine with the light of Christ.
