Ah, but the Bible also says that you can sin all you like as long as you later follow Jesus: he’s a get out of hell free card! And that it’s OK to sell your children into slavery. And I’m pretty sure you, sir, sin a hell of a lot by the lights of some of the people who claim to live by the bible.
Your knowledge of these subjects is not only very weak, but comes across as dishonest as well. To the extent that if we had this exchange with our faces and reputations on the line, you'd be savaged by my words and look like a fool. I encourage you to be more humble and also to actually contest your own claims on your own in earnestness so that you can see if those claims are actually true or just edgy hot takes from some dishonest individuals you mingled with or learned from in the past.
The Bible is against slavery. See Philemon. Sinning until the last moment doesn't count unless it's a true heart change. See Ezekiel. Treating it as a Get Out Of Hell Free card would not fly.
I would recommend instead something relevant to modern life and devoid of mysticism and muddy thinking: https://en.wikipedia.org/wiki/The_Demon-Haunted_World
