In an age of theological innovation and doctrinal discount, the heritage of evangelical Reformed theology is in increasing danger of betrayal. Old established understandings of ""the faith once delivered to the saints"" are under attack, disturbing the peace of the church, tarnishing its witness, and challenging its purity. Against the pressures of newer fashions in thought, Douglas Vickers here returns to the seventeenth-century confessions of faith and illustrates from successive chapters common to three of those confessions the ways in which, and the reasons why, traditional beliefs and doctrinal constructions are to be preserved. Among questions examined with biblically informed insight are the relation between eternity and time and its significance for the gospel of redemption, the meaning and function of saving faith, the accomplishment of redemption by the incarnate Christ, the significance of his heavenly high priestly office, the high doctrine of the Christian believer's union with Christ, and the implications these doctrinal realities hold for the Christian life. In a discussion of contemporary theologies, When God Converts a Sinner examines such innovations as the New Perspective on Paul, Federal Vision theology, Shepherdism, and other attempts to effect a paradigm shift in historically received theology. Dr. Douglas Vickers, keenly aware of historical theology and current developments, addresses vital biblical and theological issues of the day. A vigilant watchman on the walls, he provides necessary correctives to the siren songs of discordant voices heard within the church and to the minor side tracks and major derailments of contemporary theology.
