I am actually wondering about this since the age of grace will be over.
The Messages of the Three Angels
Rev 14:6 And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,
Rev 14:7 Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters.
Rev 14:8 And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication.
Rev 14:9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
Rev 14:10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
Rev 14:11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
Rev 14:12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
Rev 14:13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters.
If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
I just gave the biblical information about what I have found in the Bible related to Salvation during the Tribulation.
I believe we all shall read it, know it, and explain to others what is is stated in the book.
Now I will expose my understanding and would try to answer your question more specifically.
The ABC promoted by JD is clear: Accept, Believe, Call.
Please see that there is no other requisite for being saved. I Just have to accept I´m a sinner and understand that I need a Savior. I then have to Accept what Jesus died on the Cross for my sins and accept his gift of GRACE.
During the Tribulation this is no longer enough.
-I will have to Believe in GOD, Give Glory to Him and Worship Him.
-I will have to reject worshiping The Beast or accepting his mark.
Then what is the everlasting gospel that is preached?
[Rev 14:6 NKJV] 6 Then I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth–to every nation, tribe, tongue, and people–
The Angels are preaching the everlasting gospel, the ABCs for sure apply in this case. Why would they preach it if those who heard it could not act on it?
[Rev 7:14 NKJV] 14 And I said to him, “Sir, you know.” So he said to me, "These are the ones who come out of the great tribulation, and washed their robes and made them white in the blood of the Lamb.
There is only one way to heaven, and only one way they could have their sins forgiven, and that is by the blood of the lamb.
IMHO The age of grace does not end at the rapture, it ends when Jesus comes back to rule and reign.
Yes this is true no doubt, but at the same token, saving faith would naturally prevent this from happening for a true believer. I do not believe these proclamations by the angels are a sign of a new way to get into heaven.
I can’t imagine the situation people will be in those days, but deceptions and tyranny and societal expulsion would be not hard to imagine. Once they accept Christ as their savior, they will be able to see beyond the deception of the beast system, and gladly go to their death. Others, will love their life more than Christ, and become chaff as they accept the mark.
The simple answer is yes the ABC’s still apply.
Those who accept prior to the tribulation are the Raptured bride of Christ. To be reigning with Christ.
Those who accept during the Tribulation.
a. Those caught and don’t accept the mark are beheaded. These individuals will serve God in the temple. Rev 7:9-15
b. Those that are able to hide out and survive are the sheep (separation of Goats & Sheep) that will be living and having children during the Millennium (1000 yrs) These are the “elect” that would not have made it if God didn’t end the tribulation period.
Those people who made it through and never accepted – the Goats – are roasted.
Not all will die - some, and most likely a considerable amount will make it through. They will be who the saints reign over.
Those who were beheaded by the beast and refused the mark also reign with Christ:
Rev 20:4 NASB -
4 Then I saw thrones, and they sat on them, and judgment was given to them. And I saw the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had not worshiped the beast or his image, and had not received the mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years.
It also says Rev 7:14-15 in referring to the great multitude standing before the throne.
And he said “These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the lamb. Therefore, they are before the throne of God and serve him day and night in the temple.”
I see what you say - I guess they do both.
I have a feeling God is trying to give us a general over view of what it would be like, but describing the same thing.
Ruling and reigning, serving in the temple, worshipping I think it is describing one experience of living in our eternal state.
To some degree there is a hierarchy of sorts, by virtue of verses like
2 Corinthians 5:10 NASB — For we must all appear before the judgment seat of Christ, so that each one may be recompensed for his deeds in the body, according to what he has done, whether good or bad.
And the various crowns etc. To some will be given a little, others a lot.
