It's not so difficult. Not really.
The Bible is a collected mish-mash of the religion, poetry, myth, history, pseudo-history, and customs of a Semitic race who lived in the ancient world. (They're still with us, of course, and are a remarkable people, but the Bible isn't about modern Israel or modern Judaism.)
To understand it properly you need to know a little of their history and customs, and you need to know something of the international situation at that time.
Some years ago I was talking, through an interpreter, to a group of South Americans. It wasn't the lack of words that made it such a difficult task -- the translator was competent -- it was the lack of a common culture. Things I understood because I'd grown up with them were very mysterious to some in the group.
So it is with the Bible. To understand it you need to understand the culture of the people who wrote it.
Of course, if you think that it's God's word you're going to have trouble with all the inconsistencies and contradictions, the brutality and the immorality.
In my opinion, if the Bible had truly been written by God he wouldn't have written it in Aramaic or Hebrew, but in HTML (Hyper Text Mark-up Language) and he'd have used hyper-links. Then you wouldn't have had to ask this question.
