Graeme Goldsworthy, Preaching the Whole Bible as Christian Scripture:
We recognize that the gospel tells us of the absolutely unique work of Christ, both in His living and His dying, by which we are saved through faith. We cannot imitate or live the gospel event as such. We can only believe it. We cannot work our way into heaven by moral endeavor. We can only depend on the finished work of Christ for us. We cannot command other people to live or do the gospel. We must proclaim the message of what God has done for them in Christ. We follow the New Testament in calling on people to live out the implications of the gospel, but we cannot urge people to actually live the gospel, for that was the unique work of Christ.
