Why is understanding the two covenants important for Christians?

Christians must understand the two covenants to appreciate the distinction between their own efforts at righteousness and the sufficiency of Christ's work. The covenant of grace reaffirms that salvation is a gift from God, not earned by human actions or adherence to the law. This understanding is pivotal in our Christian walk, as it shapes our view of God's character—seeing Him as merciful and gracious rather than merely a lawgiver. The assurance that we are accepted in Christ frees believers from the bondage of sin and the curse of the law, which ultimately leads to a more profound and effective Christian life.
