It's alright to be wrong, hating to be wrong and hating to be surrounded by happy wrong people. But if you're trying to hide from fake man and preserve self-righteousness and a self-good reputation, caring more about what he thinks than what God thinks, you could find yourself hopelessly trying to hide from Him someday, foolishly asking Him if He doesn't believe all you've said and done.
They believe so much the world of fools and all the control they have in it, that they can spend their whole lives despising the existence of anything and anyone beyond that. They just don't want to know if there is and ruin the wicked dream; they are happy the way they are and it provides them with all they could ask for.
"man looks at the outward appearance, but the LORD looks at the heart"
"Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity."
