You have a perfect god, who's task is to draw people to his truth,
He wants to save people from evil and sin
agree so far? Ok cool
So, it would be a good idea to maybe give us instruction on how to live full and faithful lives, right? Right.
His instructions on how to live a life that he deems to be good is CRITICAL AND VERY IMPORTANT, since you risk being cast out of his presence FOR ETERNITY (no going back folks, sorry) and suffer in hell if you do not follow his plan. This stuff is important! He must get his word to people so they can follow it and be saved!
Ok, so we have a perfect god who wants to help save us, and he's going to give us instructions on how to love him, be pious, faithful, and good people. So whats the next logical step this perfect god makes?
He entrusts his perfect word to imperfect, greedy, lustful, hateful, racist, misogynistic people who by their very nature are TERRIBLE at communication.
Can you see where I'm going with this? This is like entrusting your only child to a pedophile as a babysitter.
It is god's fault for the misinterpretation of his teachings.
