Luke 1:79 “To give light to those who sit in darkness and the shadow of death,
To guide our feet into the way of peace.”
In the first part of Isaiah 42, we find prophecy concerning Christ. This verse is a reference to that passage. Jesus brings peace and light not just to the Jews, but to the Gentiles as well. Finding all of this from Zacharias just shows that the focus is on Christ. This is why the prophets, including John, were not always well accepted.
Heavenly Father, thank You for all of your mercy on the Gentiles. You have given Your truth to so many. May we always be faithful to share the truth. In the Name of the Lord Jesus Christ I pray and praise You, Amen.
