There are other reasons, of course, that people give for not believing. My focus in this writing is only this pop culture view of Christianity and the God of the Bible.
I think what people are saying when they say they cannot believe in the God who is described in the Old Testament is that they can’t believe in a God who seems to be (to us) so arbitrary, angry and jealous as God is portrayed in the Old Testament.
There are many things that can be said in response to this popular sentiment. For one thing, if there is a God, it doesn’t matter what I believe or what you believe: God is God regardless of our beliefs. There is Truth in the world, and it transcends me and you. The important question is, then, not what we think about God as revealed in the Old Testament, but whether it is true.
Considering whether God as revealed in the Old Testament is true should begin with some understanding of the Old Testament. In reading what people write and listening to what people say, most people (in my opinion) reject “the God of the Old Testament” or God as revealed in the Bible with very little understanding of what they are rejecting. They are rejecting a distortion or caricature. If you are going to reject something, at least understand what you are rejecting!
