Passage
Let not any one deceive you in any manner, because [it will not be] unless the apostasy have first come, and the man of sin have been revealed, the son of perdition;
Let not any one deceive you in any manner, because [it will not be] unless the apostasy have first come, and the man of sin have been revealed, the son of perdition;
2 Thessalonians 2:1 Now we beg you, brethren, by the coming of our Lord Jesus Christ and our gathering together to him,
2 Thessalonians 2:2 that ye be not soon shaken in mind, nor troubled, neither by spirit, nor by word, nor by letter, as [if it were] by us, as that the day of the Lord is present.
2 Thessalonians 2:3 Let not any one deceive you in any manner, because [it will not be] unless the apostasy have first come, and the man of sin have been revealed, the son of perdition;
2 Thessalonians 2:4 who opposes and exalts himself on high against all called God, or object of veneration; so that he himself sits down in the temple of God, shewing himself that he is God.
2 Thessalonians 2:5 Do ye not remember that, being yet with you, I said these things to you?
The verse centers on "deceive", "manner", "unless", "apostasy", "first", "come", "been", and "revealed". It is saying that the verse draws attention to "deceive" and "manner", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "that ye be not soon shaken in..." into verse 4's "who opposes and exalts himself on high...", so "deceive" and "manner" belong inside that flow. In 2 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "deceive" and "manner" with trust shaped by these words, not by a vague optimism outside the passage.
