The key is not whether we are appointed for wrath, because that refers to eternal punishment in the lake of fire. It could also refer to the bowls of God's wrath to be poured out on the earth. As I said, however, the Day of the Lord is not one minute, nor just 24 hours. It is a new age, after the church age. But that does not support the idea the majority of the church on earth at the time of Antichrist will escape the testing he is specifically authorized to inflict upon "the saints."
"Saint" is hagios
which means holy, or holy ones. The holy ones appear in Revelation a lot. Are they only raptured saints? No. Are they merely post-rapture converts? There is no evidence of that. Look at all the references to human "saints" in Revelation.
Rev. 5:8 When He had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, each one holding a harp and golden bowls full of incense, which are the prayers of the saints.
8:3 Another angel came and stood at the altar, holding a golden censer ; and much incense was given to him, so that he might add it to the prayers of all the saints on the golden altar which was before the throne. 4 And the smoke of the incense, with the prayers of the saints, went up before God out of the angel's hand.
11:18 "And the nations were enraged, and Your wrath came, and the time came for the dead to be judged, and the time to reward Your bond-servants the prophets and the saints and those who fear Your name, the small and the great, and to destroy those who destroy the earth."
13:7 It was also given to him to make war with the saints and to overcome them, and authority over every tribe and people and tongue and nation was given to him. ...
10 If anyone is destined for captivity, to captivity he goes ; if anyone kills with the sword, with the sword he must be killed. Here is the perseverance and the faith of the saints.
14: 9 Then another angel, a third one, followed them, saying with a loud voice, "If anyone worships the beast and his image, and receives a mark on his forehead or on his hand, 10 he also will drink of the wine of the wrath of God, which is mixed in full strength in the cup of His anger ; and he will be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. 11 "And the smoke of their torment goes up forever and ever ; they have no rest day and night, those who worship the beast and his image, and whoever receives the mark of his name." 12 Here is the perseverance of the saints who keep the commandments of God and their faith in Jesus.
16:6 for they poured out the blood of saints and prophets, and You have given them blood to drink. They deserve it."
17:6 for they poured out the blood of saints and prophets, and You have given them blood to drink. They deserve it."
18;20 "Rejoice over her, O heaven, and you saints and apostles and prophets, because God has pronounced judgment for you against her." ... 24 "And in her was found the blood of prophets and of saints and of all who have been slain on the earth."
19;8 It was given to her to clothe herself in fine linen, bright and clean ; for the fine linen is the righteous acts of the saints.
20;6 Blessed and holy is the one who has a part in the first resurrection ; over these the second death has no power, but they will be priests of God and of Christ and will reign with Him for a thousand years. ... 9 And they came up on the broad plain of the earth and surrounded the camp of the saints and the beloved city, and fire came down from heaven and devoured them. (MILLENIAL KINGDOM)
22:11 "Let the one who does wrong, still do wrong ; and the one who is filthy, still be filthy ; and let the one who is righteous, still practice righteousness ; and the one who is holy, still keep himself holy."
So, there you have it. The 'hagios' one is "the one who is holy, still keep[ing] himself holy". How so? Not taking the mark of the Beast, mon frere!
