It used to be that American Christians didn't need a knowledge of worldview concepts. However, American society has radically changed to where it is no longer homogeneous like it used to be. Now, we are religiously pluralistic, and consistently interact with people from many other worldviews and belief systems. It is an understanding of worldview that gives us the knowledge we need to not only effectively share the gospel to others, but also to have confidence that our beliefs are true and right.
