It's Not Rocket Science: The Theology of St. Paul the Apostle offers an understandable and usable introduction to the theology of Paul of Tarsus. By digesting and condensing the impressions and interpretations of more than one hundred other writers, Irving L. Brittle Jr., presents an approachable work that guides the reader through the main topics of St. Paul's theology centered on Jesus Christ and the wisdom of living Christians who follow the Lord.

After settling the scene by summarizing Paul's life and context, It's Not Rocket Science investigates his treatment of God, humanity, the law, sin, the Gospel, righteousness, and justification. Recognizing the key role that Martin Luther's reading of Paul has played in the life of the church over the past five hundred years, the work addresses the reformer's interpretation of St. Paul. Also, It's Not Rocket Science approaches questions of sanctification, salvation, and the sacraments.

The interpretation of the theology of St. Paul provides a concise introduction and interpretation of the apostle's theology of Jesus Christ and the nature of Christian life.
