“Arise, shine, for your light has come, and the glory of the Lord has risen upon you” (Isaiah 60:1—read Isaiah 60:1-7).
The contrast of light and darkness is one of the great recurring themes of the Bible. The first thing God created when he made the heavens and the earth was light, and then God separated the light from the darkness. John begins his Gospel writing about the Word, who is the light and the life of all people. The light shines in the darkness, and the darkness has not overtaken it. Isaiah said that the people sitting in darkness have seen a great light. Both Isaiah and Simeon called Jesus a light to enlighten the nations. Now Isaiah calls upon God’s people to arise and shine, because our light has come and the glory of the Lord has risen upon us.
Jesus told his disciples that they are the lights of the world. Jesus also declared himself to be the Light of the world. He is the primary light; his disciples are secondary lights. He shines like the sun; we shine like windows through whom the sun shines. When Jesus shines through us, his light enlightens others. As we share his promises and the good news of his victory over evil, we do our job as windows, letting his light shine into the lives of others.
Without Jesus we cannot shine. His light comes first and passes through us. Along the way, his commandments reveal our flaws and our faults. When someone washes the windows on a cloudy day, the streaks and smears might not be visible. When the sunlight shines brightly on that window, every missed spot and every speck of dirt can be seen.
We might not want Jesus to shine on us and show our sins. But the light of Jesus does something that sunlight never does to windows: his light removes the dirt and makes us pure and holy. When his light shines through us, we become clean; and because of that cleansing, the light is all the more able to shine through us to enlighten others.
Isaiah pursues that theme as he describes the nations coming to the light of Israel. Isaiah even mentions the nations bringing gifts of gold and frankincense. The wise men who followed a star to find Jesus in Bethlehem were the first of the nations to seek the light in Israel. Centurions in the Roman army also sought help from Jesus during his years of ministry, and one came into the Church early in its history through Peter’s ministry. An Ethiopian official was told about Jesus and was baptized by the deacon Philip. Paul preached to Jews and to the nations, to whomever would listen, and over the course of three hundred years the Roman Empire became a Christian nation. Now the Gospel continues to be spread throughout the world. As missionaries teach about Jesus, people hear and believe and are saved: God’s kingdom comes, and God’s will is done. Thanks be to God! J.
