Zechariah's son, John, would turn the light on in a dark world. This light would point to Jesus, the Light of the world, the Prince of Peace. John's birth happened during a dark time in Israel. The Roman Empire occupied the land, demanded high taxes, and limited freedom. Herod the Great ruled for Rome over Israel. Herod was known as a great builder, but he was an evil and violent man. The people lived in fear of what Herod might do. Israel had gone 400 years without a true prophet from the Lord. These were dark time. John the Baptist would turn on the light and point people to Christ.
We are living in a time when many people either don't know Jesus or have decided to turn their backs on Him. Our nation is becoming more and more secular. Too many of our governmental leaders are more concerned about doing what is politically correct than what is right in God's eyes. They are more concerned about holding onto power than about serving people.
Like John the Baptist, we need to turn on the Light for people to see. We need to reach out to those living in the shadows with the Light of God's Word, the Light of God's love. We need to help connect people with Jesus Christ so that He can give them the Peace that only He can give.
