You notice that I haven't said anything about belief. I began the Bible as a hopeful, but indifferent, agnostic. I wished for a God, but I didn't really care. I leave the Bible as a hopeless and angry agnostic. I'm brokenhearted about God.
After reading about the genocides, the plagues, the murders, the mass enslavements, the ruthless vengeance for minor sins (or none at all), and all that smiting—every bit of it directly performed, authorized, or approved by God—I can only conclude that the God of the Hebrew Bible, if He existed, was awful, cruel, and capricious. He gives us moments of beauty—such sublime beauty and grace!—but taken as a whole, He is no God I want to obey and no God I can love.
Unfortunately, this line of reasoning seems to leave me with several unappealing options: 1) believing in no god; 2) believing in the awful, vindictive God of the Bible; or 3) believing in some vague "creator" who is not remotely attached to the events of the Bible, who didn't really do any of the deeds ascribed to Him in the book and thus can't be held responsible for them.
My background is different (my parents were vaguely Christian, and I have oscillated between vague belief, agnosticism and atheism in my youth), but I feel with Mr. Plotz, and the option I chose is No. 1. If you believe in God's existence, you don't have this option, so I'd be interested to know how believers get around this problem (if they notice it at all).
