I'll tell you why God worship and infidelity, heaven and hell is such a big deal:
Ask the question: do you believe in God? If yes, it means you most probably pay tithe, so God is happy, his earthly lackeys are happy, you have a fair chance at heaven.
You don't believe in God? You don't pay tithe then, so you are either a heretic, pagan, or infidel. You'd do best to burn at a stake, because it will help you get used to the eternal fire that awaits you.
Easy system, really. You have to kill/burn/convert every heretic you meet, because if some get away unharmed and unconverted, not paying a tithe will spread and God's power will diminish.
