"They perish because they refused to love the truth and so be saved. And for this cause God shall send them strong delusion, that they should believe a lie . . . and so that all will be condemned who have not believed the truth but took pleasure in wickedness." 2 Thess. 10-12
The goal is to learn to love the truth. It doesn't come naturally. On the contrary, as you see it in little children even, the tendency is to lie and if allowed to proceed unchecked the child learns how to manage lying, sprinkling in just enough truth to get by. For many it becomes habitual, almost necessary like breathing, done with little extra thought or concern. Little lies, big lies and overall the whole life is a lie. The fantasies of the child become the delusions of the adult. We believe we are basically "good people" . . . when really we are ignoring or spitting in the face of God all day, every day . . . as nothing is done for His glory but instead for the glorying of the self.
And if it continues on and on, with no real pain of conscience . . . it becomes a thrill to deceive, to "get over". Eventually 2nd Thessalonians comes into play and the Lord makes it so that the rebel falls into loving a lie. Look at the situation presently--those who exult, cheer, celebrate lies made official with the stamp of government approval. They revel in the lie and they genuinely hate the truth, violently . . . with a passion.
What a terrifying thing. What a nightmare of a judgment. . . .
To be handed over to the father of lies . . . so that you can not longer even perceive truth but live only in a state of perpetual deception, a monstrous fantasy, disconnected and adrift far away, deep into the waters of wholesale destructive illusion!
Many who claim to love and follow the truth . . . do no such thing. They loosely acknowledge the Word of God, Who IS Truth itself . . . Who reveals the Creator's character, personality and attributes . . . His interaction with the creatures of time . . . but they only will see and accept those parts of His revelation which comport with their own personal predilections, likes and dislikes. . . .
They do NOT love the truth. They yet love a lie for they reject aspects of the Lord they personally disagree with, rather than see Him as He is and love all that He is and does.
They make excuses for Him--they are ashamed, embarrassed by Him and so concoct a version of Him which will not so offend the world and then they worship and extol this false god. They call Him "love" . . . but they have their own opinion what "love" is and what it looks like and how a "loving" God would be. They won't let God define "love". They reject the real God of love and instead worship the false god of lies and false "love".
Learning to love the Truth is what it's all about here. Seeking that Truth . . . then, upon finding it/Him . . . coming to Him naked, with nothing, humble to accept and glorify ALL that He reveals Himself to be.
