What is the difference between law and grace?

The difference between law and grace is a foundational theme in Christian theology. The law, given through Moses, serves to expose sin and highlight the need for a Savior, but it cannot provide salvation or mercy. In contrast, grace, which came through Jesus Christ, embodies God's love and mercy, providing forgiveness and life to those who believe. A.W. Pink noted that while the law demands righteousness, grace offers righteousness to believers through Christ's atoning sacrifice. This distinction emphasizes the futility of seeking salvation through works and the necessity of relying on grace alone.
