So encourage each other with these words.

Who is holy? God alone is holy-God the Father, God the Son (Jesus), and God the Holy Spirit. The people of God are made holy by God. What will happen to the holy people?

I have done a word search and taken 22 verses with the word ‘holy’ from the Book of Revelation. The verses describe two scenarios: the holy God and His faithful people made holy by Jesus, and the unholy people under the rule of the enemy of God. There will be persecution for the holy people of God. But Jesus will come and judge and to reward. In the meantime the holy people of God must endure persecution patiently, obeying his commands and maintaining their faith in Jesus.

Revelation 3:7 [ The Message to the Church in Philadelphia ] “Write this letter to the angel of the church in Philadelphia. This is the message from the one who is holy and true, the one who has the key of David. What he opens, no one can close; and what he closes, no one can open:

Revelation 4:8 Each of these living beings had six wings, and their wings were covered all over with eyes, inside and out. Day after day and night after night they keep on saying, “Holy, holy, holy is the Lord God, the Almighty— the one who always was, who is, and who is still to come.”

Revelation 6:10 They shouted to the Lord and said, “O Sovereign Lord, holy and true, how long before you judge the people who belong to this world and avenge our blood for what they have done to us?”

Revelation 8:4 The smoke of the incense, mixed with the prayers of God’s holy people, ascended up to God from the altar where the angel had poured them out.

Revelation 11:2 But do not measure the outer courtyard, for it has been turned over to the nations. They will trample the holy city for 42 months.

Revelation 11:18 The nations were filled with wrath, but now the time of your wrath has come. It is time to judge the dead and reward your servants the prophets, as well as your holy people, and all who fear your name, from the least to the greatest. It is time to destroy all who have caused destruction on the earth.”

Revelation 13:7 And the beast was allowed to wage war against God’s holy people and to conquer them. And he was given authority to rule over every tribe and people and language and nation.

Revelation 13:10 Anyone who is destined for prison will be taken to prison. Anyone destined to die by the sword will die by the sword. This means that God’s holy people must endure persecution patiently and remain faithful.

Revelation 14:9-10 Anyone who worships the beast and his statue or who accepts his mark on the forehead or on the hand must drink the wine of God’s anger. It has been poured full strength into God’s cup of wrath. And they will be tormented with fire and burning sulfur in the presence of the holy angels and the Lamb.

Revelation 14:12 This means that God’s holy people must endure persecution patiently, obeying his commands and maintaining their faith in Jesus.

Revelation 15:4 Who will not fear you, Lord, and glorify your name? For you alone are holy. All nations will come and worship before you, for your righteous deeds have been revealed.”

Revelation 16:5 And I heard the angel who had authority over all water saying, “You are just, O Holy One, who is and who always was, because you have sent these judgments.

Revelation 16:6 Since they shed the blood of your holy people and your prophets, you have given them blood to drink. It is their just reward.”

Revelation 17:6 I could see that she (Babylon) was drunk—drunk with the blood of God’s holy people who were witnesses for Jesus. I stared at her in complete amazement.

Revelation 18:24 In your streets flowed the blood of the prophets and ofGod’s holy people and the blood of people slaughtered all over the world.”

Revelation 19:8 She (the Lamb’s bride) has been given the finest of pure white linen to wear.” For the fine linen represents the good deeds of God’s holy people.

Revelation 20:6 Blessed and holy are those who share in the first resurrection. For them the second death holds no power, but they will be priests of God and of Christ and will reign with him a thousand years. (See below 1 Thessalonians 4:13-18 about the first resurrection)

Revelation 21:2 And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband.

Revelation 21:10 So he took me in the Spirit to a great, high mountain, and he showed me the holy city, Jerusalem, descending out of heaven from God.

Revelation 22:11 Let the one who is doing harm continue to do harm; let the one who is vile continue to be vile; let the one who is righteous continue to live righteously; let the one who is holy continue to be holy.”

Revelation 22:19 And if anyone removes any of the words from this book of prophecy, God will remove that person’s share in the tree of life and in the holy city that are described in this book.

Revelation 22:21 May the grace of the Lord Jesus be with God’s holy people.

1 Thessalonians 4:13-18 (NLT)
The Hope of the Resurrection
13 And now, dear brothers and sisters, we want you to know what will happen to the believers who have died[a] so you will not grieve like people who have no hope. 14 For since we believe that Jesus died and was raised to life again, we also believe that when Jesus returns, God will bring back with him the believers who have died.
15 We tell you this directly from the Lord: We who are still living when the Lord returns will not meet him ahead of those who have died.[b] 16 For the Lord himself will come down from heaven with a commanding shout, with the voice of the archangel, and with the trumpet call of God. First, the believers who have died[c] will rise from their graves. 17 Then, together with them, we who are still alive and remain on the earth will be caught up in the clouds to meet the Lord in the air. Then we will be with the Lord forever. 18 So encourage each other with these words.
