What role does the law play in the life of a Christian?

In Reformed theology, the law serves distinct purposes, chiefly revealing God's holy standard and our inability to meet it. As Paul states in Galatians 3:21-22, the law cannot give life but instead exposes our sinfulness, making it clear that we are all guilty before God. The law's role is not to provide a pathway to righteousness but to lead us to Christ, who fulfills the law's requirements perfectly. It is through the gospel that we find life and newness, as the Holy Spirit applies Christ's work to our lives, allowing us to live in obedience from a place of grace.
