Since no one can keep the law, what is its purpose? That may know the holy nature of God, and the sinful nature of our hearts; and thus our need for a savior. This is the 15th question in the New City Catechism and we are going to look at the three parts to this answer.

1: That we may know the holy nature of God. 2: The sinful nature of our hearts. “You have heard that it was said, ‘You shall not commit adultery.’28 But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. Matt 5-27-28 "For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin." Romans 3:20 3: And thus our need for a savior. "For it is by grace you have been saved through faith, and this not from yourselves; it is the gift of God," Ephesians 2:8 Suggested prayer from Psalm 51 1"Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. 2 Wash away all my iniquity and cleanse me from my sin."

Romans 10:9-10
