1 John 1:1-2:2
The Light of the world has come. The Light has not come as a hopeful thought, or a good inspiration. The Light has come in the flesh of a mediterranean Jew born to Mary and Joseph. The aged Apostle John bears witness to this truth. He bears witness to it, but he is not alone. He says, "We declare to you what was from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and touch with our hands, concerning the word of life...."
This enfleshment is significant. The Light in human flesh is the fulfillment of God's promise to always walk with us, to care for us, to love us, to save us. Those early disciples saw him firsthand, and now they show forth the power of being with the Light in the flesh. Jesus' physical presence in the world meant the goodness of creation could be redeemed. His physical presence proclaimed God's final judgment on anything that would try to thwart God's purposes for God's creatures and creation. The Light had come and he is making all things new.
The coming of the Light also changes what we are capable of as we live in the Light's glow. We can now have fellowship with one another. That means we can care for one another at the deepest levels of our being. It means we are capable of obedience to the Light. When we live in the Light, the blood of Jesus cleanses us from all sin. All means all. Nothing gets left out. Everything and everyone is covered by the beautiful broken body of the Light of the world.
We are not simply left to hope for better days. We are given better days by the Light. He transforms our fellowship, our relationships, our whole existence. Jesus the Light has made us holy, and we can be forever grateful that we are being changed.
Eternal God, who brings us to this new day: you gave your incarnate Son the name of Jesus to be the sign of our salvation; plant in every heart the love of the Savior of the world, Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.-The Daily Office, vol. I, The Order of St. Luke
