If the gospel is that God gives us the status of perfect righteousness, not based on our performance but simply because of his loving mercy to us in Jesus Christ, then why did God give the Law? This question has sparked massive debate within the church for the last 2000 years. Some believed that because God gave the Law, there must be something they must do to contribute to their salvation. Others have mistakenly thought that if salvation is based on grace, then it really doesn't matter how we live. But Paul argues in this passage the the Law of God is not the means of salvation, nor opposed to salvation, but a light that guides us to salvation.
