2 Thess 2:10-12
10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
11 And for this cause God shall send them strong delusion, that they should believe a lie:
12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
Thats close enough !
No one gets the prize because they were close.
In context, God sends the strong delusion because they already rejected His truth:
9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders,
10 and with all unrighteous deception
among those who perish, because they did not receive the love of the truth, that they might be saved.
11 And for this reason God will send them strong delusion, that they should believe the lie,
12
that they all may be condemned who did not believe the truth but had pleasure in unrighteousness. (2 Thess. 2:9-12 NKJ)
Prevenient Grace, God's Holy Spirit convicted them to love the truth, but they hardened their own hearts and did not receive the love of God's truth. Because they had pleasure in unrighteousness.
What was "sent". Strong delusion isn't a literal translation.
For this reason God will send upon them a deluding influence so that they will believe what is false, (2 Thess. 2:11 NAU)
God stopped restraining "satanic energy that deceives inwardly via spiritual experiences" (2 Thess. 2:7), its called the "mystery" (or secret power) that inspires people to be lawless, disobey the Bible.
But its still a choice whether one heeds their own spiritual experiences or obeys the Bible.
God won't override free will choice. Rather, He will orchestrate events so free will choice to do evil manifests itself within the appointed time, to serve God's purposes.
The book of Revelation reveals an example of this "sending". God's restraint keeping the spirits of demons in the Abyss is lifted---the door opened and out pour demon possessed locusts. The biotec Locusts permit these spirits to physically attack apostates. For five months apostates reluctant to keep following the Man of Sin as he morphs into the Seed of Satan "Son of Destruction", are tormented until they do. They want to follow the Beast, but they were reluctant knowing accepting his mark and worshipping him results in eternal torment in the lake of fire. It took five months of demonic "convincing" to get them to manifest themselves within the time allotted:
NKJ Revelation 9:1 Then the fifth angel sounded: And I saw a star fallen from heaven to the earth. To him was given the key to the bottomless pit.
2 And he opened the bottomless pit, and smoke arose out of the pit like the smoke of a great furnace. So the sun and the air were darkened because of the smoke of the pit.
3 Then out of the smoke locusts came upon the earth. And to them was given power, as the scorpions of the earth have power.
4 They were commanded not to harm the grass of the earth, or any green thing, or any tree, but only those men who do not have the seal of God on their foreheads.
5 And they were not given authority to kill them, but to torment them for five months. Their torment was like the torment of a scorpion when it strikes a man.
6 In those days men will seek death and will not find it; they will desire to die, and death will flee from them.
7 The shape of the locusts was like horses prepared for battle. On their heads were crowns of something like gold, and their faces were like the faces of men.
8 They had hair like women's hair, and their teeth were like lions' teeth.
9 And they had breastplates like breastplates of iron, and the sound of their wings was like the sound of chariots with many horses running into battle.
10 They had tails like scorpions, and there were stings in their tails. Their power was to hurt men five months.
11 And they had as king over them the angel of the bottomless pit, whose name in Hebrew is Abaddon, but in Greek he has the name Apollyon.
(Rev. 9:1-11 NKJ)
