This document discusses the challenge of moral relativism for Christians witnessing in today's world. It defines moral relativism as the view that moral truths are subjective and determined by individuals rather than being objectively true. There are three types of relativism discussed: what a society does is true for them, what a society says is right, and what the individual thinks is right. The document argues that if moral relativism is true, then there is no universal morality, no basis for the gospel or Christianity, and the Bible has no meaning. It concludes that Christians must learn to distinguish moral claims from preferences and engage skillfully with moral relativists.
