The narrative of the angels’ appearance is found in Luke 2:13-15.
The teaching of Jesus as the light of the world (refrain) is found in John 1:4-9 and 8:12
When stanza 3 speaks of the “Prince of Peace” see Isaiah 9:6.
In stanza 2 of “Jesus, the Light of the World,” “the nations” rise to joyfully praise Jesus and come to his light. Our World Belongs to God, paragraph 21, leads us to profess that the Lord promised to be God to Abraham and Sarah and their children, “blessing the nations through them” and shaping them to be a people who will be “a light to the nations.” In these words we catch a glimpse of what Heidelberg Catechism teaches us in Lord’s Day 21, Question and Answer 54, that Christ “through his Spirit and Word”…will gather a church “from the entire human race.”
In stanza 4, Jesus is proclaimed as the “heaven-born Prince of Peace.” We also hear Our World Belongs to God, paragraph 54 identifying him as the “Prince of Peace,” and calling us all to be “peacemakers,” walking in the ways of peace and calling on our governments to work for peace.
