1. To give knowledge of salvation (76-78a)
Zechariah's son was not the Christ. He was John the Baptist, the forerunner of the Messiah. He was sent by God to prepare the way for Christ's coming. How does one prepare for the coming of the Lord? John's ministry called people to repentance. He proclaimed forgiveness of sin. Our great human problem is sin. Jesus came to solve this problem by dying for our sins and rising from death. John made people aware of sin and he heralded Jesus the Savior.
2. The rising Sun (78b-80)
At the time of Jesus' coming, the world was clothed in the dark night of sin. My life was also dark and meaningless before Jesus came to me. Jesus' coming is like the rising sun. He shines his light of salvation and life on those living in the darkness of sin and fear, under the shadow of death.
Application: Lord, help me to be a herald of Jesus. Help me to prepare a way for him to come into the dark lives of the people of my time.
One Word: Jesus turns darkness into light
