Luke 1:76-79: "'And you, child, will be called the prophet of the Most High; for you will go before the Lord to prepare his ways, to give knowledge of salvation to his people in the forgiveness of their sins, because of the tender mercy of our God, whereby the sunrise shall visit us from on high to give light to those who sit in darkness and in the shadow of death, to guide our feet into the way of peace.'"
Isaiah 60:1-3: "Arise, shine, for your light has come, and the glory of the LORD has risen upon you. For behold, darkness shall cover the earth, and thick darkness the peoples; but the LORD will arise upon you, and his glory will be seen upon you. And nations shall come to your light, and kings to the brightness of your rising."
Isaiah 60:19-20: "The sun shall be no more your light by day, nor for brightness shall the moon give you light; but the LORD will be your everlasting light, and your God will be your glory. Your sun shall no more go down, nor your moon withdraw itself; for the LORD will be your everlasting light, and your days of mourning shall be ended."
Ephesians 5:8-14: "For at one time you were darkness, but now you are light in the Lord. Walk as children of light (for the fruit of light is found in all that is good and right and true), and try to discern what is pleasing to the Lord. Take no part in the unfruitful works of darkness, but instead expose them. For it is shameful even to speak of the things that they do in secret. But when anything is exposed by the light, it becomes visible, for anything that becomes visible is light. Therefore it says, 'Awake, O sleeper, and arise from the dead, and Christ will shine on you.'"
Isaiah 25:7-9: "And he will swallow up on this mountain the covering that is cast over all peoples, the veil that is spread over all nations. He will swallow up death forever; and the Lord GOD will wipe away tears from all faces, and the reproach of his people he will take away from all the earth, for the LORD has spoken. It will be said on that day, 'Behold, this is our God; we have waited for him, that he might save us. This is the LORD; we have waited for him; let us be glad and rejoice in his salvation.'"

The text is public domain:
Hark! A thrilling voice is sounding!
"Christ is near," we hear it say.
"Cast away the works of darkness,
All you children of the day!"
Startled at the solemn warning,
Let the earth-bound soul arise;
Christ, its sun, all sloth dispelling,
Shines upon the morning skies.
See, the Lamb, so long expected,
Comes with pardon down from heav'n.
Let us haste, with tears of sorrow,
One and all, to be forgiv'n;
So, when next He comes in glory
And the world is wrapped in fear,
He will shield us with His mercy
And with words of love draw near.
Honor, glory, might, dominion
To the Father and the Son
With the ever-living Spirit
While eternal ages run!

The "thrilling voice" in the first line seems to refer to John the Baptist. The Luke 1 text cited is Zechariah's prophecy about him, and the lines in the hymn seem to reference Matthew 3:1-3: "In those days John the Baptist came preaching in the wilderness of Judea, 'Repent, for the kingdom of heaven is at hand.' For this is he who was spoken of by the prophet Isaiah when he said, 'The voice of one crying in the wilderness: "Prepare the way of the Lord; make his paths straight."'" The "thrilling voice" is "the voice of one crying in the wilderness" (quoting Isaiah 40:3), and the hymn's "'Christ is near'" is something of a paraphrase of "'The kingdom of heaven is at hand.'"
The next quotation though ("'Cast away the works of darkness, / All you children of the day!'") comes from the Ephesians text, specifically: "Take no part in the unfruitful works of darkness, but instead expose them" and "Walk as children of light."
"Let the earth-bound soul arise" in the second verse seems to come from "'Awake, O sleeper, and arise from the dead'" from Ephesians, although Isaiah 60:1-3 also has the imperative "arise." The third line's calling Christ the sun refers to Isaiah's "Your sun shall no more go down... for the LORD will be your everlasting light."
I think the third verse comes from the Isaiah 25 text. There aren't any specific phrases in common, but both mention tears, waiting for the Lord, and the salvation that He will bring.
