“To redeem them that were under the law, that we might receive the adoption of sons.”
King James Version (KJV)
4:5 To redeem those under the law - From the curse of it, and from that low, servile state. That we - Jews who believe. Might receive the adoption - All the privileges of adult sons.
Ga 4:5 To redeem them that were under the law. Those under bondage need redemption in order to secure freedom. Paul has shown that those under the law were in bondage. From this bondage Christ came to redeem us. How the redemption was wrought is shown in Ga 3:13. That we might receive the adoption of sons. This "adoption of sons" is bestowed as a gift. We cannot have it, and still be in bondage.
