A practical understanding of the new covenant is important to each believer. The apostle Paul wrote an entire letter to the church at Galatia because the church was preoccupied with a mixture of the new and old covenants and he warned that this was becoming a real problem. In fact, he referred to this perversion as “another gospel” in Gal 1:6. The devil would like nothing more than to water down Christianity by addition and subtraction to rob the Christian of his joy and his freedom (Galatians 5:1). This work is intended to help believers understand the dynamics of the new covenant as Jesus taught them through John’s Gospel and other Scriptures. The transition from the old covenant to the new covenant was a real struggle for the first century church as evidenced by the first church council in Jerusalem (Acts 15). Just as the Apostle Peter had difficulty with it, this struggle continues today through many different movements which undermine the purity of the gospel of grace and cause great division within the church. Having a firm grasp of the important dynamics of the new covenant allows us to discern when the devil tries to pervert the truth and helps bring believers into the abundant life that Jesus had intended each believer to experience!
