In the Galatian churches those who advocated keeping the ceremonial law saw themselves as being loyal to the Old Testament. Paul in response wants to show that it is a belief in salvation through faith that truly is being faithful to the Old Testament (v6).

Those who have faith in the Lord Jesus are spiritual children of Abraham (v7). This shows there is a great continuity in salvation between the Old and new Testaments. In both Testaments it is through faith in the Lord’s salvation that saves. In the Old Testament people were saved by looking forward in faith to the salvation to come in Jesus. Since the New Testament times people are saved by looking back in faith in the salvation provided in Jesus.

People who trust in Jesus are saved through the covenant made with Abraham which promised that through his seed all the world would be blessed (v8, Genesis 22 v18). There is only one salvation which is always through faith in the Lord Jesus. Those with faith are in good company with Abraham the man of faith (v9). Is your faith in Christ alone?
