If the Bible is metaphorical then perhaps so is the God of the Bible

To those who only take certain parts of the Bible literally, how do you determine where the metaphors end and the facts begin? Maybe God Himself is simply a metaphor for something else like the forces of nature.

Bible Literalists at least claim to take the entire Bible literally.How do you decide what you know to be untrue?

Most Christians take the story of the resurrection literally. How could they have come to that conclusion by comparing statements in the Bible with reality?

That's basically the same thing, unless they pick and choose certain parts of the Bible to compare with reality and turn a blind eye to other parts.I'll rephrase then: how do Christians decide which parts of the Bible are true?

I've run into the same problem many times. In this thread I'm hoping to understand their rhyme or reason.

That is possible, although I've spoken to Christians who claim to have studied the Bible comprehensively and are still somehow able to differentiate between the metaphor and the literal.

Are you saying they assume the stories of the Bible are true until proven otherwise?

I appreciate all of the responses, but I mostly agree with them and therefore don't have much to add. I encourage everyone to please keep replying because I value your opinions, but I would like to hear from some Christians as well.

Yes, I'm interested in authorial intent. How do Christians determine that the authors intended the Genesis creation account to be metaphorical, but the story of the resurrection was intended to be literal?

If you want to ask a different question and answer it in your own thread, please do so, but that's NOT the question I'm asking in this thread, so please do not clutter this thread with off topic posts.

I meant: How do Christians decide which parts of the Bible are literally true and which parts are meant to be metaphorical?

Are there similar metaphorical indicators in the creation story of Genesis?

Is it really so unclear what I'm asking? How do Christians determine which stories of the Bible are intended to be metaphorical and which parts are to be taken literally?

Well is the creation story to be taken literally?
