Why is the Bible so long and confusing?
The Bible is not a single book; it is a library of 66 books that were written over a period of over 2000 years in two (or possibly 3) dead languages – Koine Greek, ancient Hebrew, and ancient Aramaic. The confusing part for me is that it still speaks to us today and its message is still relevant.
Each of the authors was writing to a specific group of people with a certain purpose. Amazingly, the Bible hangs together and has hung together since the first Council of Nicaea in 325 AD (the first church convention). When one thinks about it, it is amazing that one book can contain so many different points of view. Genesis 1 says the world was created in 7 days. Genesis 2 tells a different creation story. The central message of the Bible is unchanged—that Jesus is the risen Christ.
The Bible can be long and confusing or it can be interesting and inspiring. If you READ it from the basis of faith, I am sure you can find some viewpoints you agree with, and other things you disagree with or find confusing. That's ok! Many of us will agree with you. I have one friend that is compiling a list of "Jesus Questions” – questions of things in the Bible or life that confuse her on Earth. She plans to ask Jesus these questions when she gets to heaven. The one thing I'm certain of is that all these books were written by people of faith, giving witness to the God who raised Jesus from the dead. If you read it as a book of faith stories, perhaps you won't get hung up on the details.
