The Apostle Paul tells us that Christ made known the mystery to him, and then he made this good news known to others. Understanding the mystery, or previously hidden truth, is the key to understanding your Bible. We learn in this lesson that the mystery includes the gospel of grace, the formation of the Body of Christ, and Christ’s heavenly ministry as Head of the Church. Understanding this revelation distinguishes God’s prophetic plan for Israel from His mystery program for the Church. With the mystery now revealed, the Church is commissioned to make it known so all can see God’s grace and be transformed by it.
