In Galatians 4, Paul builds upon his argument that believers are justified by faith and explains the privileges that belong to those who are in Christ. Before faith in Christ, people were spiritually like children under guardians, unable to enjoy the full rights of inheritance. But through Jesus Christ, God has adopted believers as His sons and daughters, giving them the full privileges of His family.
Paul expresses deep concern that the Galatians are turning back toward legalism by observing religious days, months, seasons, and years as though these practices could improve their standing before God. He reminds them of their warm reception when he first preached the gospel and pleads with them not to abandon the freedom they found in Christ.
The chapter concludes with the allegory of Hagar and Sarah. Paul uses these two women to illustrate the difference between seeking righteousness through the Law and receiving God's promises through faith. Those who belong to Christ are children of the promise and are called to live in the freedom that God provides.
“But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law, to redeem those who were under the law, that we might receive the adoption as sons.”
Galatians 4:4–5, NKJV
God's plan of salvation unfolded at exactly the right time. Jesus came to redeem those under the Law so that all who believe in Him could become members of God's family through adoption.
“And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, ‘Abba, Father!’ Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ.”
Galatians 4:6–7, NKJV
Believers enjoy a personal relationship with God as their Father. Through the Holy Spirit, Christians are no longer slaves living in fear but beloved children who share in God's inheritance.
“But now after you have known God, or rather are known by 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, NKJV
Paul warns that returning to legalistic religion is a step backward rather than forward. Having experienced God's grace, the Galatians should not return to systems that cannot provide salvation or spiritual maturity.
“My little children, for whom I labor in birth again until Christ is formed in you.”
Galatians 4:19, NKJV
Paul's pastoral heart is evident as he longs to see Christ's character fully developed in the lives of the believers. Christian maturity is measured by increasing conformity to Christ rather than external religious performance.
One of the great blessings of salvation is adoption. Through faith in Christ, believers are welcomed into God's family with all the rights and privileges of sons and daughters. This relationship is based entirely on God's grace.
Paul contrasts the freedom found in Christ with the bondage of legalism. Returning to the Law as a means of gaining God's favor is like returning to slavery after being set free.
Paul's goal was not merely that the Galatians possess correct doctrine, but that Christ's life be increasingly reflected in their character. Sound theology should produce spiritual transformation.
Using the example of Hagar and Sarah, Paul illustrates the difference between human effort and God's promise. Those who trust in Christ belong to the line of promise and inherit God's blessings through faith, not through the works of the Law.
Chapter 4 concludes Paul's doctrinal defense of justification by faith. Having demonstrated that believers are children of promise rather than slaves under the Law, Paul is now prepared in chapters 5 and 6 to explain how Christians should live in the freedom that Christ has secured for them.
Galatians 4 reminds believers that Christianity is founded on a relationship with God, not merely religious activity. Because we have been adopted into God's family, we serve Him out of love rather than out of fear or a desire to earn His acceptance.
The chapter also encourages us to evaluate whether our spiritual lives are marked by joyful dependence upon Christ or by confidence in religious performance. True spiritual growth comes as Christ is formed within us through the work of the Holy Spirit.
Because we have been adopted into God's family through Jesus Christ, we are called to live as children of promise, enjoying the freedom of God's grace rather than returning to the bondage of legalism.
