In Galatians 3, Paul shifts from defending his apostleship to explaining the biblical foundation of the gospel. He challenges the Galatians for abandoning the truth they had already experienced. Having received the Holy Spirit through faith, they were now being persuaded that spiritual maturity came through keeping the Law.
Paul points to Abraham as the great example of justification by faith. Long before the Mosaic Law was given, Abraham was declared righteous because he believed God (Genesis 15:6). This demonstrates that God's plan of salvation has always been based on faith rather than works.
Paul also explains the purpose of the Law. The Law was never intended to provide salvation but to reveal sin and point people to Christ. Now that Christ has come, all who place their faith in Him are sons and daughters of God and heirs of the promises made to Abraham.
“Just as Abraham ‘believed God, and it was accounted to him for righteousness.’ Therefore know that only those who are of faith are sons of Abraham.”
Galatians 3:6–7, NKJV
Paul reminds his readers that Abraham was justified by faith before the Law existed. The true children of Abraham are those who share his faith, not merely his physical ancestry.
“But that no one is justified by the law in the sight of God is evident, for ‘the just shall live by faith.’”
Galatians 3:11, NKJV
Quoting Habakkuk 2:4, Paul emphasizes that righteousness before God has always been received through faith. The Law reveals God's standard but cannot make sinners righteous.
“Therefore the law was our tutor to bring us to Christ, that we might be justified by faith.”
Galatians 3:24, NKJV
Paul describes the Law as a tutor or guardian whose role was to lead people to recognize their need for a Savior. Once faith in Christ has come, believers are no longer under the Law as a means of justification.
“For you are all sons of God through faith in Christ Jesus.”
Galatians 3:26, NKJV
Every believer enters God's family through faith in Christ. Our relationship with God is based on His grace, not on ethnic background, religious tradition, or personal achievement.
“There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.”
Galatians 3:28, NKJV
Paul teaches that every believer shares equal standing before God. While distinctions among people continue to exist in everyday life, they do not determine a person's acceptance, value, or inheritance in Christ.
Paul demonstrates from the Old Testament that salvation by faith was not a new idea. Abraham's justification occurred centuries before the giving of the Law, showing that faith has always been the means by which people are made right with God.
The Law is holy and good, but it was never intended to save. It exposes sin, reveals humanity's need for redemption, and directs people to Christ, who alone provides forgiveness and righteousness.
God's promise to Abraham came before the Law and cannot be cancelled by it. The inheritance God promised is received through faith in Christ, the ultimate fulfillment of that promise.
Everyone who trusts in Jesus becomes part of God's family. Regardless of nationality, background, or social status, believers share the same standing before God and the same inheritance as children of Abraham through faith.
Having defended the gospel in chapters 1 and 2, Paul now uses Scripture to show that justification by faith has always been God's plan. Chapter 3 lays the theological foundation that continues into chapter 4, where Paul explains the privileges of being God's adopted children and heirs through Christ.
Galatians 3 reminds believers that our relationship with God has always been based on faith, not performance. While obedience is an important part of the Christian life, it is the result of salvation rather than the means of earning it.
The chapter also encourages Christians to find their identity in Christ instead of in personal accomplishments, religious traditions, or cultural distinctions. Every believer stands equally before God because of His grace.
God has always justified people by faith, and through Jesus Christ all who believe become His children and heirs of His promises.
