The passage discusses the challenges that theists face in holding religious beliefs within a postmodern worldview. Postmodernism promotes the ideas that individuals determine their own truths and that God is unnecessary in people's lives. However, theism can still be practiced by relying on core Christian beliefs, such as God's love for humanity as expressed through Jesus, and the afterlife consequences of following or rejecting God. The passage argues that evil exists due to human free will and disobedience rather than being God's doing.
