What is a worldview?
Greg Bahnsen defined it this way; “A worldview is a network of presuppositions (which are not verified by the procedures of natural science) regarding reality (metaphysics), knowing (epistemology), and conduct (ethics) in terms of which every element of human experience is related and interpreted.” Nothing is neutral. “You must not set aside your faith in God when you consider anything.” Your worldview must be consistent with the revelation in the Bible. A house divided cannot stand. When parts of your worldview do not comport with the Scriptures things need to change. “He who is not with Me is against Me, and he who does not gather with Me scatters abroad” (Matt 12:30).

War of the Worldviews
"In the 1939 movie The Wizard of Oz, a tornado carries Dorothy and Toto to a faraway land. When they arrive, Dorothy says, "Toto, I have a feeling we're not in Kansas anymore." Many Christians feel the same sense of unease about the culture in which they now find themselves. Non-Christian ideologies and philosophies are now the norm. In this session, Dr. R.C. Sproul Jr. seeks to equip the church to intelligently engage this brave new world."
