Galatians 2:18
For if I build again the things which I destroyed, I make myself a transgressor.
Galatians 2:18 (KJV)
Context
The apostle Paul wrote the book of Galatians to the churches in Galatia, where false teachers were promoting legalism. In Galatians 2, Paul defends the truth that a person is justified by faith in Christ, not by works of the law. The immediate question in verses 15-17 is whether the gospel makes Christ a minister of sin. Paul answers with verse 18: rebuilding the system of law-justification that Christ set aside proves a person to be a transgressor.
Key Themes:
The Gospel of Grace: Throughout Galatians, Paul defends the gospel of grace, which teaches that salvation is obtained through faith in Jesus Christ alone, not by observing the works of the law. Attempting to rely on works for salvation nullifies the grace of God.
Transformation and New Life: The phrase “building again the things which I destroyed” describes a person who, having embraced grace and freedom in Christ, turns back to legalistic practices or tries to earn salvation through works. Paul cautions against such a return, highlighting the danger of becoming a transgressor, someone who goes against God’s intended plan of salvation.
The Futility of Legalism: Legalism is strict adherence to religious rules as a means of obtaining salvation. Paul had formerly been a zealous Pharisee who strictly followed the Jewish law, but he discovered the emptiness of relying on external practices alone. In this verse, he warns against rebuilding the very things he had realised were powerless to secure salvation.
Meaning
Paul uses the first person as a general proposition: anyone who rebuilds what he has torn down proves himself a transgressor. The “things destroyed” refers to the system of justification by the law, including the rites and ceremonies of the Mosaic law, which were abrogated in Christ. To rebuild that system—by word or practice—is to declare oneself a lawbreaker, because it denies the sufficiency of Christ’s work and returns to a mode of righteousness that the law itself cannot provide. The verse is not about rebuilding good things; Paul’s former destruction of the faith of the gospel was wrong, but his current building up of the gospel is right. Rather, it is about reinstating what God has set aside. The phrase “I make myself a transgressor” points to individual responsibility: by resorting to legalism, one rebels against the true message of the gospel.
Biblical connections
This verse connects directly to Galatians 2:19, where Paul says he died to the law through the law, so that he might live to God. This reinforces that the believer is united to Christ in His death, and the old system has no claim. Paul’s argument is not that the law is sinful, but that using it as a means of justification is a transgression of the gospel. The believer’s life is now lived by faith in the Son of God, who loved and gave Himself (Galatians 2:20).
Application
Embrace the Gospel of Grace: Salvation is a gift from God, received by faith in Jesus Christ. We cannot earn it through our own efforts or works. Guard against any inclination to rely on legalistic practices as a means of achieving righteousness.
Beware of False Teachings: Just as the Galatian church was influenced by false teachings, we must be cautious of any ideologies or beliefs that deviate from the gospel of grace. Study God’s Word diligently and seek the guidance of the Holy Spirit to discern truth from error.
Live in Freedom: Through faith in Christ, we have been set free from the bondage of sin and the law. Do not willingly subject ourselves to unnecessary burdens or engage in legalistic practices that hinder spiritual growth. Embrace the freedom we have in Christ and live in accordance with His teachings and the leading of the Holy Spirit.
Personal Accountability: Recognise the responsibility each believer has to maintain a vibrant relationship with God. Avoid tendencies to revert to old patterns or practices that contradict the message of grace. We are called to walk in obedience and pursue a life that reflects the transforming power of God’s grace.
Reflection
Galatians 2:18 reminds us of the importance of clinging to the gospel of grace and not returning to legalistic practices. We are saved by faith in Jesus Christ, and any attempt to rely on works for salvation undermines the grace of God. Let us live in the freedom Christ has given us, being careful not to rebuild the things that have been destroyed by His redemptive work.
