Ok, so Chapter 6 of Hebrews is all about perseverance and not giving up. It's like, don't be a quitter, you guys. It's saying that it's impossible to renew people who have apostatized and that it's impossible to bring them back to repentance. So, basically, don't give up on your faith, cuz you can't take it back. It's like, once you're baptized, there's no going back and that's it. You're stuck. You don't want to be like Judas, and all those other Biblical characters who turned away from the Lord, because then you're just gonna be in a world of trouble. Ya feel me?
