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.
14You are the light of the world. A city built on a hill cannot be hid. 15No one after lighting a lamp puts it under the bushel basket, but on the lampstand, and it gives light to all in the house. 16In the same way, let your light shine before others, so that they may see your good works and give glory to your Father in heaven.
17Do not think that I have come to abolish the law or the prophets; I have come not to abolish but to fulfill. 18For truly I tell you, until heaven and earth pass away, not one letter, not one stroke of a letter, will pass from the law until all is accomplished. 19Therefore, whoever breaks one of the least of these commandments, and teaches others to do the same, will be called least in the dominion of heaven; but whoever does them and teaches them will be called great in the dominion of heaven. 20For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the dominion of heaven.”
