The triune nature of God is one of the core doctrines of the Christian faith and distinguishes Christianity from all other belief systems. Yet, the Trinity has continued to be challenged throughout history and is a watershed issue of our time. How does God define Himself, and how do we explain to others the God of the Scriptures? Mike Oppenheimer's book demonstrates that the Bible-in both Old and New Testaments-is absolutely definitive in portraying the Lord God as one God, while maintaining three distinct persons-Father, Son, and Holy Spirit. It also examines the qualities and characteristics of each of these persons according to Scripture.With over 300 Bible verses, Oppenheimer's Trinity book will serve as both a standard and a witnessing tool in understanding the triune nature of God from a biblical perspective.
