It’s 2 Thessalonians and you have taken one verse out of context.
King James Bible
The Man of Sin
1Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
3Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
4Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
It is the exact opposite of what you just said.
You stopped too soon.
2 Thess 2:6-8 says ONLY AFTER the Holy Spirit is taken away will “that Wicked” be revealed. And you should know that the only way the Holy Spirit can be taken away is we also are taken away because the Holy Spirit is in us.
