The Kingdom of God: A Baptist Expression of Biblical & Covenant Theology explains why the maze of the Old and New Testaments cannot be properly navigated or understood without a knowledge of the dual (law and gospel) nature of the Abrahamic Covenant. For the law of the Old Covenant and the grace of the New Covenant flow out of the Abrahamic Covenant and are wonderfully reunited in the gospel of Jesus Christ. In other words, out of the earlier dichotomy comes the later unity of the gospel message.
