God sends a delusion?

[Telstra Robs]

2 Thessalonians 2:9-12

"The coming of the lawless one is by the activity of Satan with all power and false signs and wonders, 10and with all wicked deception for those who are perishing, because they refused to love the truth and so be saved. Therefore God sends them a strong delusion, so that they may believe what is false, in order that all may be condemned who did not believe the truth but had pleasure in unrighteousness."

What does it mean by "therefore God sends them a strong delusion, in order that all may be condemned who did not believe the truth but had pleasure in unrighteousness"?

the same as in romans chap 1

8 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. 19 For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. 21 For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. 22 Claiming to be wise, they became fools, 23 and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.

24 Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, 25 because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen.

26 For this reason God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; 27 and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error.

28 And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. 29 They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips, 30 slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents, 31 foolish, faithless, heartless, ruthless. 32 Though they know God's decree that those who practice such things deserve to die, they not only do them but give approval to those who practice them.

[PaulSacramento]

In a nutshell, if you willingly and knowingly turn your back on God, he will give you what you ask for.
God does not turn his back or anyone nor does God "send a delusion" inot the heart of anyone so they will not believe, that would be cruel and unloving of God.
No, God gives people what they want- free will- and people are free to believe in God or write God off as "nonsense" and when they do that, God gives them what they want.
It's not the same as a person that doesn't know about God, no it is not that.
It is a person that KNOWS about God and chooses to "turn their back" on God, basically the "blasphemy of the HS" thing.

well said Paul, I'll just add that

if you do not know God personally but are arrogant enough to be dis-obedient at all costs, then it applies too.
