That we may know the holy nature and will of God, and the sinful nature and disobedience of our hearts; and thus our need of a Savior. The law also teaches and exhorts us to live a life worthy of our Savior
No, but because of the disobedience of our first parents, Adam and Eve, all of creation is fallen; we are all born in sin and guilt, corrupt in our nature and unable to keep God’s law.
Since the fall, no mere human has been able to keep the law of God perfectly, but consistently breaks it in thought, word, and deed.
You shall have no other gods before me. You shall not make for yourself an idol in the form of anything in heaven above or on the earth beneath or in the waters below—you shall not bow down to them or worship them. You shall not misuse the name of the Lord your God. Remember the Sabbath day by keeping it holy. Honor your father and your mother. You shall not murder. You shall not commit adultery. You shall not steal. You shall not give false testimony. You shall not covet
Personal, perfect, and perpetual obedience; that we love God with all our heart, soul, mind, and strength; and love our neighbor as ourselves. What God forbids should never be done and what God commands should always be done.
