In Christ, We Are No Longer Slaves but Sons and Daughters of God
Paul continues explaining the incredible privilege believers have through Christ. He compares life under the Law to that of a child who, although an heir, is still under guardians and has not yet entered into the full privileges of adulthood. Then Paul declares:
“But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law.” — Galatians 4:4
This is one of the clearest statements in Scripture about God’s perfect timing. Jesus did not come by accident. He came at exactly the moment God had planned. Why?
“…to redeem those who were under the law, that we might receive the adoption as sons.” — Galatians 4:5
Paul then gives one of the most beautiful descriptions of our relationship with God:
“And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, ‘Abba, Father!’” — Galatians 4:6
“Abba” expresses the close, personal relationship believers now enjoy with God. Paul concludes:
“Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ.” — Galatians 4:7
The Gospel does more than forgive sinners. It welcomes them into God’s family.
This reminds us that our identity has been completely transformed through Jesus Christ. We are no longer slaves trying to earn God’s acceptance or living in fear of rejection. Instead, we have been adopted into His family as His beloved children. This means we can approach God with confidence, knowing that He is our loving Father who cares for us personally. Our relationship with Him is not based on performance but on His grace. Every one of us should live with the security, joy, and confidence that comes from knowing they belong to God and are heirs of all that He has promised through Christ.
Don’t Return to Spiritual Bondage
After reminding the Galatians of their new identity, Paul expresses deep concern. He asks:
“But now after you have known God… how is it that you turn again to the weak and beggarly elements, to which you desire again to be in bondage?” — Galatians 4:9
The Galatians had experienced the freedom of the Gospel. Yet they were being tempted to return to a system of religious rules as though these could make them more acceptable to God. Paul was heartbroken. He reminds them of how warmly they had once received him and how eager they had been to embrace the truth. Now false teachers were trying to win them over for selfish reasons. Paul compares himself to a mother in labour:
“My little children, for whom I labor in birth again until Christ is formed in you.” — Galatians 4:19
His deepest desire was not merely that they believe the right doctrine, but that Christ would increasingly be formed in their lives.
This chapter reminds us never to exchange the freedom found in Christ for any form of spiritual bondage. Whether it is legalism, self-righteousness, or relying upon religious performance, anything that shifts our confidence away from Christ ultimately robs us of the joy of the Gospel. God’s desire is not merely that we follow rules but that Christ is formed within us. Spiritual maturity is measured not by outward performance alone but by the growing presence of Christ’s character in our lives. The more we know Him, the more our lives should reflect Him.
Choose the Freedom of God’s Promise Over the Slavery of Human Effort
Paul concludes the chapter by using an illustration from the life of entity[“people”,”Abraham”,”biblical patriarch”]. He speaks about Abraham’s two sons:
– entity[“people”,”Ishmael”,”son of Abraham”], born to Hagar, the bondwoman. – entity[“people”,”Isaac”,”son of Abraham”], born to Sarah through God’s promise. Paul explains that these two women represent two covenants. Hagar represents the covenant associated with Mount Sinai and slavery under the Law. Sarah represents the covenant of promise and freedom through God’s grace. Paul concludes:
“So then, brethren, we are not children of the bondwoman but of the free.” — Galatians 4:31
The lesson is clear. Believers belong to the covenant of grace. Their standing before God rests upon His promise fulfilled in Christ, not upon human effort.
This reminds us that Christianity is built upon God’s promises rather than human performance. Just as Isaac was born through God’s miraculous promise, believers become children of God through His gracious work rather than through their own achievements. We must continually resist the temptation to place our confidence in religious activity, personal goodness, or human effort. True freedom is found in resting completely upon what God has accomplished through Christ. As children of promise, we are called to live joyfully in the liberty that His grace has secured for us.
Deeper Waters
Galatians 4 deepens Paul’s argument by moving from the doctrine of justification to the believer’s identity as a child of God.
The chapter begins with the imagery of adoption. In the ancient world, an adopted son received full legal standing within the family. Paul uses this picture to show that believers are no longer spiritual minors living under guardianship but fully accepted members of God’s household through Christ.
The phrase:
“But when the fullness of the time had come…” — Galatians 4:4
reveals God’s sovereign control over history. The coming of Christ was not random but occurred at the exact moment determined by the Father, fulfilling His redemptive plan.
Paul’s use of “Abba, Father” reflects the intimate relationship Jesus Himself enjoyed with the Father. Through Christ, believers are brought into that same family relationship, not merely as servants but as sons and daughters.
The latter half of the chapter uses the historical account of Hagar and Sarah to illustrate two fundamentally different approaches to God:
– one based on human effort and bondage, – the other based on divine promise and freedom.
Paul is not denying the historical reality of Genesis but drawing a theological lesson from it. The contrast reinforces the central message of Galatians: salvation rests upon God’s promise fulfilled in Christ, never upon human works.
Paul’s heartfelt statement:
“…until Christ is formed in you.” — Galatians 4:19
reveals his pastoral goal. He is not content with believers merely professing faith. His longing is that their lives increasingly reflect the character of Christ. Galatians 4 encourages us to: rejoice in their adoption into God’s family, resist every form of spiritual slavery, live confidently as heirs of God’s promises, and pursue a life in which Christ is continually being formed within them.
Ultimately, Galatians 4 points us to Jesus Christ. He came at the Father’s appointed time to redeem those under the Law, adopt them into God’s family, and give them the Holy Spirit. Through Him, believers move from slavery to sonship, from fear to intimacy, and from striving to resting in God’s promises. The chapter beautifully reminds us that the Christian life is not about earning a place in God’s family—it is about living joyfully as children who have already been welcomed home through the grace of Christ.
