Romans 3:19, 20, 27, 28

Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God.

Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin.

Where, then, is boasting? It is excluded. Because of what law? The law that requires works? No, because of the law that requires faith.

For we maintain that a person is justified by faith apart from the works of the law.
