"But when the fullness of the time was come, God sent forth his Son, made of a women, made under the law, to redeem them that were under the law, that we might receive the adoption of sons.” (vv.4-5)
At just the right time, Jesus Christ came to purchase all who were under the law, who were trying hard to obey it, but powerless to do so. “Born of a woman” is a simple phrase underscoring an amazing truth of Jesus’ human birth: the Incarnation, “God with us.” “Made under law” refers to the Mosaic Law, which until Christ no one had kept perfectly (Rom. 8:3). In the overall context of Galatians, we can conclude from these two phrases that Jesus was a perfect human being.
In keeping with God’s plan, He (Jesus) redeemed us--that is, He paid the price necessary to free us from the “slave market” of sin. More than that, He adopted us into His family with the “full rights of sons” (v. 5). We went from being slaves of sin to children of God, from condemned prisoners on death row to inheritors of heaven (v. 7; Rom. 8:17)!
Adoption is a beautiful thing, especially when done by believers who want to show the heart of God. We ourselves are a reflection of God’s heart, for we are adopted children of our heavenly Father. But, adoption is not the means of entry into God’s family, but the privilege and standing we receive within God’s family. The only means of entry, as Jesus told Nicodemus in John chapter 3 is, “One must be born again.” The moment that happens we are placed in an adopted state, heirs to the riches of the Father, and have the Spirit of His Son in our hearts. Therefore, we can call God “Abba, Father” (v.6) – and He will respond.
What a beautiful progression. First we are set free from slavery. Then we are declared sons and adopted into God’s family. Then, as sons, we are made heirs. Heirs inherit something and Paul made it clear just what we inherit: an heir of God through Christ and we inherit God Himself (v.7). For some, this might seem like a small inheritance. Yet for those who are really in Christ and who really love God, to be an heir of God is the richest inheritance of all.
The Truth: “For as many as are led by the Spirit of God, these are sons of God. For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father.” The Spirit Himself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and joint heirs with Christ.” (Romans 8:14-17)
