You can not take every word in the Bible literally. It was not meant to be a literal factual scientific document. It was written to teach people the Word of God.
How do I know which words are literal and which are not? How can I learn the Word of God if what is written in the Bible can't be understood by reading?
Do I read the book and know, in my heart, what is and what isn't? What if I find that none of it should be taken literally?
Do I seek out someone to tell me which words are literal and which are not? There are so many people that want to tell me how but they all tell me different things. Is an older church better? A newer church? A popular church? One that supports a more literal interpretation or a less literal interpretation?
Should I listen to you? You say you have it all figured out. So does the Pope. And Warren Jeffs. Why would I listen to you instead of one of them? Why would I listen to one of them instead of you?
