Why is understanding the difference between the law and gospel important for Christians?

The distinction between law and gospel is crucial in Reformed theology as it ensures that believers comprehend how salvation is achieved and maintained. The law reveals God's standards and our inability to meet them, while the gospel proclaims the good news of salvation through Christ. Galatians 2:16 cautions against adding laws or works to the gospel, which can lead to a corrupted understanding of grace. By maintaining this distinction, Christians can preserve the purity of the gospel and understand that salvation is a free gift through faith, not by works. This clarity helps believers avoid legalism and ground them in the assurance of Christ's completed work.
