What is a worldview and how is it related to the origins debate. This lecture defines worldview and the important questions that it addresses. Dr. Mortenson gives three reasons why every Christian needs to understand the role of worldviews in this controversy. He explains key points of a truly biblical worldview and the naturalistic worldview that dominates science. He then shows that many Christians today do not have a biblical worldview, which is why they are compromised with millions of years or even with biological evolution.
