“All who rely on observing the law are under a curse, for it is written: ‘Cursed is everyone who does not continue to do everything written in the Book of the Law.’ Clearly no one is justified before God by the law, because, ‘The righteous will live by faith.'” (Galatians 3:10-11)
Paul’s concern throughout Galatians was for the truth, the unity of the church, for the edification of believers and the salvation of the lost. He wanted to uphold the truth of the gospel which freed the Gentile believers (and all believers) from the requirements of the law. He also desired to see that all believers held equal status in the Church as they did before the Lord. This he does by proclaiming the central truths of the Christian faith: all believers are incapable of keeping the Law but all believers are in Christ so all receive the benefits of His atoning sacrifice. Essentially then, no amount of law keeping by humans can bring them closer to God. Christ keeps the law for us and through us.
Paul teaches that the righteous must live by faith, trusting in God’s promises even in the midst of doubt, uncertainty and turmoil. Those who have such faith no longer have to worry that God will condemn. He offers mercy, forgiveness, wisdom and strength to those who come to Him knowing that without His help, no one can live a life of perfect righteousness even if he or she tried to. Believers can live in righteousness only as they rely on Christ. Salvation does not depend on good works, piety or the keeping of the law, or failure to do so. Salvation is by faith in the righteousness of Christ, in His atoning work on the cross. The benefits of His work are granted to all those who are know this and are humble, broken and who surrender themselves to His will.
