Passage
And therefore God shall send them strong delusion, that they should beleeue lies,
And therefore God shall send them strong delusion, that they should beleeue lies,
2 Thessalonians 2:9 Euen him whose comming is by the effectuall working of Satan, with all power, and signes, and lying wonders,
2 Thessalonians 2:10 And in al deceiuablenes of vnrighteousnes, among them that perish, because they receiued not the loue of the trueth, that they might be saued.
2 Thessalonians 2:11 And therefore God shall send them strong delusion, that they should beleeue lies,
2 Thessalonians 2:12 That all they might be damned which beleeued not the trueth, but had pleasure in vnrighteousnes.
2 Thessalonians 2:13 But we ought to giue thankes alway to God for you, brethren beloued of the Lord, because that God hath from the beginning chosen you to saluation, through sanctification of the Spirit, and the faith of trueth,
The verse centers on "therefore", "shall", "send", "strong", "delusion", "should", "beleeue", and "lies". It is saying that the verse draws attention to "therefore" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "And in al deceiuablenes of vnrighteousnes among..." into verse 12's "That all they might be damned which...", so "therefore" and "shall" 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 "therefore" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
