VERSE 5. That we might receive the adoption of sons. Paul still has for his text Genesis 22:18, "In thy seed shall all the nations of the earth be blessed." In the course of his Epistle he calls this promise of the blessing righteousness, life, deliverance from the Law, the testament, etc. Now he also calls the promise of blessing "the adoption of sons," the inheritance of everlasting life. What ever induced God to adopt us for His children and heirs? What claim can men who are subservient to sin, subject to the curse of the Law, and worthy of everlasting death, have on God and eternal life? That God adopted us is due to the merit of Jesus Christ, the Son of God, who humbled Himself under the Law and redeemed us law-ridden sinners.
