Psalm 85:7-8: "7 Show us your steadfast love, O LORD, and grant us your salvation.
"8 Let me hear what God the LORD will speak, for he will speak peace to his people, to his saints; but let them not turn back to folly."
1 John 4:10: "In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins."
Revelation 7:9-17: "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.
"15 'Therefore they are before the throne of God, and serve him day and night in his temple; and he who sits on the throne will shelter them with his presence. 16 They shall hunger no more, neither thirst anymore; the sun shall not strike them, nor any scorching heat. 17 For the Lamb in the midst of the throne will be their shepherd, and he will guide them to springs of living water, and God will wipe away every tear from their eyes.'"
2 Corinthians 5:17: "Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come."

Psalm 85:7-8 and 1 John 4:10 both seem to appear in the first verse, especially in the title line ("Love divine, all loves excelling"). "God is love" from 1 John 4:16 could also be cited, particularly for the lines "Jesus, Thou art all compassion, / Pure, unbounded love Thou art."
The other two cited passages appear in the fourth verse. 2 Corinthians 5:17 is referred to at the beginning, in the line "Finish then Thy new creation." The passage from Revelation 7 is summarized at the end of the verse, although the line "Till we cast our crowns before Thee" refers to Revelation 4:9-11 (particularly verse 10): "9 And whenever the living creatures give glory and honor and thanks to him who is seated on the throne, who lives forever and ever, 10 the twenty-four elders fall down before him who is seated on the throne and worship him who lives forever and ever. They cast their crowns before the throne, saying, 11 'Worthy are you, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they existed and were created.'"
+++
The line "Let us find Thy promised rest" in the second verse seems to refer to Matthew 11:28: "'Come to me, all who labor and are heavy laden, and I will give you rest.'"
The title "Alpha and Omega" in the second verse comes from Revelation (1:8; 21:6; 22:13).
