That is what atheists say about GOD and the entire bible.
If we do not understand what GOD does, is that automatically evil?
I never understod why an innocent animal had to be sacraficed? In a way I think that is cruel, yet it is a commandment of GOD and I have faith he knows what he is doing even if I don’t.
Sacrificing animals isn’t mandatory and there are examples where sin was forgiven without shedding blood. Shown you that before.
