In Chapter 11, we stood in the divine courtroom. We saw the Judge bang the gavel and declare the guilty sinner “Righteous” based on the work of Christ. That is the glory of Justification—it settles our legal status. But God does not merely release us from the dock and tell us to go live our lives as law-abiding citizens. He does something far more shocking. He comes down from the bench, removes His judicial robes, and takes us home.
This brings us to Chapter 12 and the doctrine of Adoption. While Justification deals with our legal standing, Adoption deals with our relational standing. It moves us from the courtroom to the family room. Many theologians have called this the highest privilege of the gospel, for while a judge can acquit a criminal, he rarely adopts him.
The Confession teaches that all justified believers are adopted into God’s family in Christ, granting them the status, liberties, and privileges of children, including access to the Father, the indwelling Spirit, fatherly provision and discipline, and an irrevocable inheritance.
The Basis of Our Sonship
The Confession begins by linking adoption directly to justification: “All those that are justified, God vouchsafeth… to make partakers of the grace of adoption.” You cannot be a child of God without first being declared righteous by God.
But what is the basis of this new status? It is “in and for His only Son Jesus Christ.” We are not God’s children by natural birth; by nature, we are “children of wrath” (Eph. 2:3). We are children only by a legal act of adoption. Here we see the marvelous exchange: In Christ, we become by grace what he eternally is by nature. As John 1:12 declares, “But to all who did receive him, who believed in his name, he gave the right to become children of God.” We are brought into the family solely because we are united to the Elder Brother.
The Spirit and the Name
This adoption is not just a title; it is an experience. The Confession lists the incredible “liberties and privileges” we enjoy. First, we “have His name put upon them” (Rev. 3:12). Just as an adopted child takes the surname of their new father, we bear the name of the Triune God.
Furthermore, we “receive the spirit of adoption” (Rom. 8:15). God does not just give us the legal papers; He puts His Spirit inside us to change our hearts toward Him. This allows us to “have access to the throne of grace with boldness” and enables us to “cry, Abba, Father” (Gal. 4:6). “Abba” is a term of intimacy, similar to “Papa” or “Dad.” In the Old Testament, approaching the Holy of Holies was fatal for anyone but the High Priest. Now, the humblest believer can run to the Creator of the Universe and climb into His lap.
Fatherly Care and Discipline
Being in the family means we are under the Father’s care. The divines list three tender verbs: we are “pitied, protected, provided for.” As a father pities his children (Ps. 103:13), so the Lord pities those who fear Him. He knows our frame; He remembers we are dust. We do not need to be anxious about what we will eat or drink, for our heavenly Father knows we need them (Matt. 6:32).
However, being a son also means being trained. The Confession honestly states we are “chastened by Him as by a Father.” When we sin, God does not punish us as a Judge (that penalty was paid by Christ); He disciplines us as a Father (Heb. 12:6). This discipline is not a sign of His hatred, but a proof of His love. It is painful, but it yields the peaceful fruit of righteousness.
An Inheritance That Cannot Fade
Finally, the Confession assures us of our security. An earthly father might disown a rebellious child, but God’s adoption is permanent. We are “never cast off, but sealed to the day of redemption.” The Holy Spirit is the seal—the down payment—guaranteeing that we belong to God (Eph. 4:30).
Because we are children, we are “heirs of everlasting salvation” (Rom. 8:17). We “inherit the promises.” The inheritance is nothing less than the world, the kingdom, and God Himself. Justification delivers us from hell; Adoption prepares us for heaven. It reminds us that the Christian life is not a cold adherence to rules, but a warm, living relationship with a Father who loves us, a Savior who calls us brother, and a Spirit who whispers to our spirit that we are His.
