“What purpose then does the law serve? It was added because of transgressions, till the Seed should come to whom the promise was made…” (Galatians 3:19).
Paul’s reasoning until v. 25 have sometimes been mistakenly interpreted to mean that all the divinely revealed codes of laws in the OT ended with Calvary. And some have mistakenly concluded that in pre-Christian era men were saved by the keeping of the law, and in the Christian Era by grace through faith. But such a view is contrary to the whole body of Scripture.
God has had only one way saving man, that is, by faith in the sacrifice of our Lord. This salvation has been declared to man for all times (Heb. 4:2). Paul himself affirmed that grace did not abolish the law: “Do we then make void the law through faith? Certainly not! On the contrary, we establish the law” (Rom. 3:31).
It is evident, therefore, that whatever Paul is teaching in Galatians 3:19–25 he is not teaching the doctrine of a pre-Christian era of salvation by law versus a Christian Era of salvation by grace. What he is truly teaching becomes evident when we understand that there are two different laws:
Called “the law of Moses” (Luke 2:22).
Called “law … contained in ordinances” (Ephesians 2:15).
Written by Moses in a book (2 Chronicles 35:12).
Placed outside the ark (Deuteronomy 31:26).
Ended at the cross (Ephesians 2:15).
Added because of sin (Galatians 3:19).
Contrary to us, against us (Colossians 2:14).
Judges no one (Colossians 2:14-16).
Carnal (Hebrews 7:16).
Called “the law of the Lord” (Isaiah 5:24).
Written by God on stone (Exodus 31:18; 32:16).
Placed inside the ark (Exodus 40:20).
Will stand forever (Luke 16:17).
Points out sin (Romans 7:7; 3:20).
Not grievous (1 John 5:3).
Judges all people (James 2:10-12).
Spiritual (Romans 7:14).
Perfect (Psalms 19:7).
Moses’ law foreshadowed the cross and ended at Christ’s death. This law was added till the “seed should come,” and that “seed … is Christ” (Galatians 3:19, 16). However, God’s moral law stands forever, for Paul spoke of it as holy, just, and good many years after the cross (Romans 7:7, 12).
