Biblical backgrounds is essential for anyone wanting to move forward in their understanding of God's Word.
That means understanding the history, the geography, the genre, the themes of each book, and the time the book was written. Many mistakes in interpreting the Bible would be solved if people would look at the context of the passage, the chapter, the book, the Testament, the Bible and Jesus Christ.
The context is so important, and you just cannot rip verses out of context and expect to have a coherent understanding of what God was doing for his people at that time, and which parts apply to today.
This is basic hermeneutics or Bible Interpretation. Then, we do need to pray and ask the Holy Spirit to use the backgrounds to really show us how it applies to our lives.
I would disagree with the fact that the prophets disagreed with each other. I have read the Bible from cover to cover at least 50 times, and studied it myself, in Seminary and in church. When there are apparent contradictions, CONTEXT usually explains the issue. God is not the author of confusion.
