Oh, please. Biblical interpretation is simplicity itself. The Bible means exactly what it says, except when it doesn't, and you can tell which is which because everyone who knows the Bible knows the difference even when no one agrees on what any of it means or what the differences are.
You'd probably appreciate this website:
www.biblegateway.com
you can put in one verse and select all the different verisons/translations of the Bible. Find which interpretation suits you best and go with that verison of the Bible! (Actually, it's a pretty interesting site. You can see where the confusion between different Christian sects comes in)
Often, the rule of thumb appears to be, "if what it la passage iterally says is something I agree with, then it means exactly that, and if what it literally says is not something I agree with, then it's figurative, or needs to be considered in a larger context, or allegorical, or a different convenant, or... just one of those parts we try to put out of our minds".
