The Law of God is good — it’s just that we sinners cannot save ourselves by the Law. Salvation is a free gift of God because that is the only way we could ever be saved. The Law shows us God’s holiness and thus our own sin. And now in Christ we can look at the Law and see it in a new light as well: as a guide for how to live a godly life in thanksgiving to God for His gracious forgiveness in Christ.
