So brethren, the point Paul clearly made in 2 Thessalonians 2 should never be forgotten. The sentence is so straightforward that anyone should be able to understand what is written.
2 Thessalonians 2:1-4 (NKJV) 1 Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, 2 not to be soon shaken in mind or troubled, either by spirit 9or by word or by letter, as if from us, as though the day of Christ had come. 3 Let no one deceive you by any means; for [that Day will not come] unless the falling away comes first, and the man of sin is revealed, the son of perdition, 4 who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
Once again, Paul said "let no man deceive you by any means, for that day (the day of Christ's return) shall NOT come until there is a great apostasy when the man of sin, the son of perdition is revealed."
Now then, given the revelation of that “man of sin” which is Satan (the ANTICHRIST), how can anyone read that line and yet believe that Christ can return at any time?
Satan comes first before Jesus.
