In this sermon at Castle Pines Community Church, Douglas Groothius offers a useful overview of religious and moral relativism. He talks about Jesus as a thinker and a model for us in communicating truth and approaching intellectual problems. Groothius shows the importance of apologetics, and valuing the Christian worldview as true in both our own Christian walk and in talking with unbelievers.
