Revelation 15:3-4: "3 And they sing the song of Moses, the servant of God, and the song of the Lamb, saying, 'Great and amazing are your deeds, O Lord God the Almighty! Just and true are your ways, O King of the nations! 4 Who will not fear, O Lord, and glorify your name? For you alone are holy. All nations will come and worship you, for your righteous acts have been revealed.'"
Revelation 7:9-14: "9 After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, 10 and crying out with a loud voice, 'Salvation belongs to our God who sits on the throne, and to the Lamb!' 11 And all the angels were standing around the throne and around the elders and the four living creatures, and they fell on their faces before the throne and worshiped God, 12 saying, 'Amen! Blessing and glory and wisdom and thanksgiving and honor and power and might be to our God forever and ever! Amen.'
"13 Then one of the elders addressed me, saying, 'Who are these, clothed in white robes, and from where have they come?' 14 I said to him, 'Sir, you know.' And he said to me, 'These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb."
Jude 25: "to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen."

Glory be to God the Father,
Glory be to God the Son,
Glory be to God the Spirit:
Great Jehovah, Three in One!
Glory, glory
While eternal ages run!
Glory be to Him who loved us,
Washed us from each spot and stain;
Glory be to Him who bought us,
Made us kings with Him to reign!
Glory, glory
To the Lamb that once was slain!
Glory to the King of angels,
Glory to the Church's King,
Glory to the King of nations;
Heav'n and earth, your praises bring!
Glory, glory
To the King of glory sing!
Glory, blessing, praise eternal!
Thus the choir of angels sings;
Honor, riches, pow'r, dominion!
Thus its praise creation brings.
Glory, glory,
Glory to the King of kings!

The text from Revelation 7 appears in the second verse ("Washed us from each spot and stain" comes from verses 13-14) and in the fourth verse ("Thus the choir of angels sings" comes from verses 11-12, and "Thus its praise creation brings" comes from verses 9-10).
The phrase "before all time and now and forever" from Jude 25 seems to be appear as "while eternal ages run" in the first verse.
The title "King of the nations" from the text from Revelation 15 appears in the third verse.
And, of course, all three of the texts that are cited mention glorifying God, which is present in each of the hymn's verses.
