Theological, historical, and doctrinal differences between the Bible and the Koran are examined in Charles R. Floyd's book A Comparative Analysis of the Bible with the Koran. Crucially examining biblical inequalities, societal effects, and interpretations, it draws attention to significant variations in themes such as grace, mercy, works, and redemption. The study's provocative findings inspire readers to learn more about scripture and faith.

The Holy Bible is regarded as the inerrant word of God and serves as the foundation of Christian faith. It emphasizes the principles of divine grace, salvation through faith, and the importance of a personal relationship with God.
The Holy KORAN is regarded as the central religious text of Islam, believed to be the word of Allah as revealed to Prophet Muhammad. It emphasizes the importance of good works, submission to Allah, and a structured moral and spiritual path.
