John himself was not the light; he was simply a witness to tell about the light. The one who is the true light, who gives light to everyone, was coming into the world.
— John 1:8-9 NLT
John wasn't the light. No, the true light was going to come for everyone. John's ministry was primarily in the desert and to Israelites, but his message wasn't to prepare just Israel for the Messiah. No, we all need his message. Unlike John, the Messiah wasn't going to set up his ministry in the desert and have people come to him. The true light was coming into the world to save all the world. He was going to shine for all people: men and women, slaves and free, Jew and Gentile.  Since Jesus is the true light, since he died for our sins and saved us, and since we are his disciples, we need to ask ourselves a crucial question: "What are we — what am I — doing to make sure that everyone gets to know Jesus, God's true light for the world?" Let's be a part of letting the world know that God sent his Son to make salvation available to everyone! 
O Father, give me a bigger heart for those that I don't know. Use me to share Jesus with those outside my cultural comfort zone. Give me a greater sensitivity to those around me so that they can experience your love and welcoming grace because of the way I treat them. In Jesus' name, I pray. Amen.
