John Byl argues that the Christian worldview provides the only foundation for logic, mathematics, science and morality. The Divine Challenge aims to substantiate this bold claim. Byl shows the failure of today’s predominant philosophies to provide a coherent worldview that can yield a plausible account of the various aspects of life as we experience it. Only a Christian worldview, squarely based on the truth of the Bible and the comprehensive sovereignty of God, can give our lives coherence, meaning, purpose and hope.
