When Jesus began his ministry the first sermon he preached issued the following command: ‘Repent and believe in the gospel’ (Mark 1:15). But of what were people to repent? Is there a clear moral standard in the Bible that reveals the holiness of God, the sinfulness of man, and the purity of new life in Christ? Yes, there is. The place of the moral law in relation to the gospel has become one of the most controversial issues for the evangelical church today. The end result is that less than 1% of church members can list the ten commandments. It is sadly true that some preach the law without the gospel. Some preach neither the law nor the gospel. However, no matter how hard many try, you cannot genuinely preach the gospel without the law. It is hoped that this small volume may be used of God in awakening zeal for his glory, encouraging faithful preaching, promoting wise living, and initiating true revival.
