The Bible and Lutherans teach that God wrote his law in people's hearts at creation. The human conscience bears witness to that law. The knowledge of the law was blurred in people's hearts by sin. God repeated his law in the Ten Commandments. God's law demands obedience in our thoughts, speech, and actions. It condemns all who sin. Therefore no one can be saved by keeping the law. God's law serves to show us our sins, to warn us of God's anger against sin, and to guide us in our Christian life.

The LORD wrote on those tablets what he had written before, the ten commandments he had proclaimed to you on the mountain.

Be perfect therefore, as your heavenly Father is perfect.

Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin.

Whoever keeps the whole law and yet stumbles at just one point, is guilty of breaking all of it.

How can a young man keep his way pure? By living according to your word.
