Over the past 2,000 years, humans have discovered great knowledge from science, theology, and personal experiences of life that clarify or change our understanding of various Biblical tenets and assumptions. Ancient people knew nothing of physics, biology, chemistry, or astronomy when they authored the Bible. Today, there are passages of Scripture that may not fit our modern knowledge. Keeping Faith in the 21st Century seeks to foster discussion and dialogue among Christians with questions or doubts about the Bible's relation to this modern knowledge. This work is inspired by the author's personal experience and questions in hopes to promote respectful conversation instead of "I'm right, you're wrong" accusations.
