Preaching Grace
Doctrine is the necessary basis for a sound spiritual life, and defective doctrine almost inevitably leads to a distorted spiritual life. Nowhere is this truth more evident than in understanding the relationship between the old covenant law and the gospel, which is a theological issue with enormous practical implications. Its importance was recognized by Martin Luther, who could write that “whoever knows well this art of distinguishing between Law and Gospel, him place at the head and call him a doctor of Holy Scripture.” The gospel always demonstrates that God’s perfect law and His love were fulfilled on the cross of Christ. To lose the balance will always lead to spiritual deformity because, if either “law” or “love” is absent from the life of God’s people, the gospel will fail to operate in its God-intended way.
