Read Deuteronomy chapter 28 for some perspective. The whole thing. If god exists, (which I've found myself doubting lately), no less this specific one written about in Hebrew, then he is capable of causing to become incomprehensible cruelty. Think about what it would take for anyone to not only orchestrate and maneuver but also desire the kinds of abhorrent barbarity written about in Deuteronomy 28 and much of the bible, to be executed onto you personally. Surely a sickening thought.
Any rational person should be moved to the realization that fear and superstition no longer functions today like it did back then. Of course you won't be driven by god to eat your own children. If that happens, you are 100% to blame for choosing to do that. But please don’t, I’ll send you some animal crackers. Likewise, if something bad happens to someone who leaves the organization, it’s simply a product of chance …or a combination of chance, poor decision-making, and maybe ignorance (all likely caused by damaging psychological effects and emotional baggage, not to mention the healthy required serving of guilt).
If this god really exists and truly desires to carry out such divine punishments on petty ignorant and imperfect human beings, the universe is much bigger than it needs to be for such a tiny worldview.
Any human would consider the leader of a nation who behaved exactly as YHWH did as behaving immorally much of the time. Surely the god of the universe and his morality would supersede and be 'righter' than any human’s. Of course, it’s possible we've fallen so far from perfection that our innate sense of righteousness is so wrong that human suffering is really a universal good thing. But again, superstition holds no place here.
All that being said, it certainly isn't easy to scan those verses and not think about it, as ridiculous as it reads. Like it’s been said, the realization that I could be wrong is what educates me and I’ve found myself coming towards radically different conclusions than I ever would’ve expected as a kid or teenager. But I’m still willing to be wrong about TTATT, and maybe that’s why folks like you and I hold onto fear. I haven’t left by the way.
