What does the Bible say about the Spirit versus the letter of the law?

In 2 Corinthians 3:6, the Apostle Paul contrasts the letter of the law with the Spirit, stating that the letter kills but the Spirit gives life. This distinction is crucial for understanding salvation in Christ. The 'letter' refers to the written law, which can highlight sin but cannot impart life or righteousness. In contrast, the Spirit of God works internally in the hearts of believers, bringing them to true faith and freedom in Christ. A true understanding of the Scriptures reveals Christ, transforming believers through grace rather than through mere adherence to the law.
