Greetings in the name of the Lord Jesus Christ. As a USAF retired systems engineer turned Baptist Preacher of the Gospel of our Lord Jesus Christ, and armed with a staunch belief in the preserved accuracy of the inspired Scriptures, I praise the Lord that he has provided me the unique opportunity to assemble A Systematic Theology for the 21st Century. As a systems engineer for thirty years (since 1972), I focused on systems analysis. Systematic theology has intrigued me ever since my first Bible institute course in 1975. I have amassed multiple systematic theology books and never found one that is wholly Biblical. In 2013 my seminary work at Louisiana Baptist Theological Seminary, under Dr. Steven Pettey, assigned me to read and analyze six volumes of Systematic Theology by Lewis Sperry Chafer, the founder and previous president of Dallas Theological Seminary. Initial critique of this neo-evangelical's voluminous, wordy, often unorganized work, answered the question, Is there not a cause? A Systematic Theology for the 21st Century is indeed a valid need. It cried out to be written and it was a work that I was privileged to endeavor.
