What does the Bible say about living under the law versus living by faith?

Scripture contrasts living under the law with living by faith throughout the epistles, emphasizing that the law brings condemnation, while faith in Christ secures justification. In Galatians 3, Paul addresses the Galatians, warning them against returning to the bondage of legalism, which he refers to as spiritual foolishness. He reminds them, 'having begun in the Spirit, are you now made perfect by the flesh?' (Galatians 3:3). This highlights the importance of remaining dependent on grace rather than turning to works for validation of righteousness. The law, represented through Moses, cannot lead to salvation; instead, it condemns, while faith in Christ is the means through which we receive salvation and the Spirit.
