The Bible makes many promises and offers a lot of advice. Can you really trust promises and advice from such an old book?
Barb, Focus on practicing the behavioral themes referred to in the Bible, and ignore or minimize the things you can't do anything about. I view the Bible as an example of how to live in harmony with the better half of the world, the creative side, not the destructive side.
Our universe requires balance to function, it's the balance between good and bad, or creation and destruction, both are required.
Your reality is based on what you believe, think about and practice. It's that simple.
