Luke 1:78 Because of God’s tender mercy, the morning light from heaven is about to break upon us, 79 to give light to those who sit in darkness and in the shadow of death, and to guide us to the path of peace.”
Zacharias began to prophesy concerning the great things God was doing in the birth of John the Baptist and Jesus. At the end of His prophecy he speaks of God’s great mercy. God’s plan was never to leave humanity in darkness, cut off from relationship with Him, but to shine a great light in the middle of that darkness and display His marvelous light. He wasn’t sending just a messenger, or another prophet, this time He was coming Himself in the person of Jesus to display the heart of God to a world that had been separated from Him. He would show us what humanity was created to look like and how we could walk in His peace. He would remove every obstacle to loving God and make a way where there was no way. Nothing is impossible for God.
