In the end - the fate of the devil and his angels do not concern me. It is mankind that I’m concerned with mostly. However God chooses to deal with His adversaries is entirely up to Him.
I agree, but I believe God states clearly how he will deal with His adversaries, and in my opinion, the universalists are teaching a different doctrine.
St. Paul asserts, 1 Cor 6:9 “
do you not know that the unrighteous will not inherit the kingdom of God?” Anyone asserting that their is not a class of people who will not inherit the kingdom of God is incorrect.
Rev 18:23 speaks of a class of deceivers who will no longer see the light of Christ, never again hear His voice. How will these ever inherit the kingdom of God?
Rev 18:23 (KJV) "And the light of a candle shall shine no more (Gk “ou me”) at all in thee; and the voice of the bridegroom and of the bride shall be heard no more (Gk “ou me”) at all in thee: for thy merchants were the great men of the earth; for by thy sorceries were all nations deceived.
Likewise, in Rev., after heaven and earth are renewed, a category of people will be cast into the same lake of fire as the devil and his angels. These are those who are not written in the Lamb’s book of Life. The dead are judged “according to their deeds.” (Rev 20:12).
Rev 20 pertains to the final judgment. Rev 21 is the renewal of heaven and earth. Even after the judgement of God, and the renewal of heaven and earth, the fate of two classes of people are contrasted …
Rev 21:7-8 “
He who overcomes will inherit these things, and I will be his God and he will be My son. "But for the cowardly and unbelieving and abominable and murderers and immoral persons and sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death.”
Rev 21:27 “
and nothing unclean, and no one who practices abomination and lying, shall ever (Gk “ou me”) come into it, but only those whose names are written in the Lamb’s book of life.”
According to Thayer, the Greek expression “ou me” signifies “not at all, in no wise, by no means.” There will be some, the unjust according to St. Paul, who will not, by no means whatsoever, come into the kingdom of God.
It is difficult for me to then conclude that there exists another means for these after the day of judgement, already judged to be unjust by Christ, who are not written in the book of life, to come into the kingdom of God.
Universalists seems to suggest that everybody is written in the Lamb’s book of life, but that makes nonsense of the above Scripture passage.
