And there are always going to be others who embrace the bad stuff, and question the good. And at the very least, you'd have a debate on your hands as to who was being more faithful to the bible.
And hey, I can appreciate that you are agnostic and questioning. Your rejection of the bad parts of the bible is to be commended. But those parts will always be there, waiting for the next person to take them seriously.
I know, they will, for now. But I have faith that they don't have to be. I'm an agnostic believer/ SBNR who identifies as Christian but ultimately doesn't like labels and categories anyway. I don't expect that to make sense to you.
Basically, I think people are better off to not read the Bible if they are already set on doing good and it's only being used to confuse them via fear and control. But if it can be looked at and discerned for good, by compassionate actions, then it's okay.
