The Place of the Law
After God gave the promise to Abraham, he gave the law to Moses. Why? He had to make things worse before He could make them better. The law exposed sin, provoked sin, condemned sin. The purpose of the law was to lift the lid off man’s respectability and disclose what he is really underneath — sinful, rebellious, guilty, under the judgment of God and helpless to save himself.
And the law must still be allowed to do its God-given duty today. One of the great faults of the contemporary church is the tendency to soft-pedal sin and judgment… We must never bypass the law and come straight to the gospel. To do so is to contradict the plan of God in biblical history… No man has ever appreciated the gospel until the law has first revealed him to himself. It is only against the inky blackness of the night sky that the stars begin to appear, and it is only against the dark background of sin and judgment that the gospel shines forth.”
–John Stott, Galatians, pp. 92-93.
