(15) "For behold, the LORD will come in fire, and his chariots like the whirlwind, to render his anger in fury, and his rebuke with flames of fire. For by fire will the LORD enter into judgment, and by his sword, with all flesh; and those slain by the LORD shall be many.

(17) "Those who sanctify and purify themselves to go into the gardens, following one in the midst, eating pig's flesh and the abomination and mice, shall come to an end together, declares the LORD. "For I know their works and their thoughts, and the time is coming to gather all nations and tongues. And they shall come and shall see my glory,
…

(23) From new moon to new moon, and from Sabbath to Sabbath, all flesh shall come to worship before me, declares the LORD.
(24) "And they shall go out and look on the dead bodies of the men who have rebelled against me. For their worm shall not die, their fire shall not be quenched, and they shall be an abhorrence to all flesh."

In the end God will excerise revenge against all those that have rejected His son, Jesus Christ; but you can be saved by believing in the Lord Jesus Christ (John 3:16).

The sinful condition of the world judged here, existed in the days of the prophet Isaiah. It was only God’s patience that allowed Israel and the Nations to continue in it. Evil is fully consummated when Israel rejected her Messiah (See Matthew 12), and the Antichrist comes to lead the unfaith completely and irresolvable away from God, after which the final judgement will come.
