Book excerpt: Popular claims about the old and new covenants have diminished the gospel and narrowed the faith and spiritual life of millions of Christians. Those claims have introduced confusion about what it truly means to "keep the commandments of God and the faith of Jesus." Christians earnest in their walk with the Lord will see a dynamic element of the gospel in the profound relationship between love and law. They will, perhaps for the first time, understand the apparent dichotomy of old and new covenants in the New Testament. And in the process they will be confronted with a powerful appeal and an unmistakable warning.
