Yeah I get what you mean. I hear that a lot too.
But remember God has a plan. So does he plan for me to commit sin and thus his punishment is in itself planned, which just seems mean and unnecessary... Or did I go against his plan when I sinned and now has to punish me, and if that is the case he seems quite fallible.
So god is either mean or fallible, which to me seems like a god not worth worshipping.
I am probably just overthinking this and need sleep.
