2 Corinthians 4:4-6: "4 In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. 5 For what we proclaim is not ourselves, but Jesus Christ as Lord, with ourselves as your servants for Jesus' sake. 6 For God, who said, 'Let light shine out of darkness,' has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ."
Hebrews 12:1-2: "1 Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, 2 looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God."
1 John 1:5: "This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all."
Revelation 21:23: "And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb."

The verses from 2 Corinthians seem to be the primary Biblical source for the hymn, although no specific phrases are taken from them, just the image of "the light of the gospel of the glory of Christ."
The title line ("I want to walk as a child of the light") is from Ephesians 5:8: "For at one time you were darkness, but now you are light in the Lord. Walk as children of light." The third line of the first verse ("God set the stars to give light to the world") references Genesis 1:14-16, where God creates the stars.
The second verse contains the line "Clear Sun of Righteousness, shine on my path," which uses a title from Malachi 4:2: "But for you who fear my name, the sun of righteousness shall rise with healing in its wings. You shall go out leaping like calves from the stall." The "shine on my path" part uses an image from Psalm 119:105: "Your word is a lamp to my feet and a light to my path."
"Let us run with endurance the race that is set before us" from Hebrews 12 appears in the third verse: "When we have run with patience the race...."
The refrain draws from a few verses. It begins with "In Him there is no darkness at all," which is from 1 John 1:5. The next line is "The night and the day are both alike," which seems to come from Psalm 139:12: "Even the darkness is not dark to you; the night is bright as the day, for darkness is as light with you." The next line ("The Lamb is the light of the city of God") is from Revelation 21:23.
