Romans 1, 2 and 3 make plain that people are condemned for their willful, voluntary rejection of the knowledge of God which they already have, that God has written His law on the hearts of the Gentile as well as the Jew, and that all have nevertheless sinned and come short of the glory of God.Now we know that whatever the law says, it says to those who are under the law, that every mouth may be stopped, and all the world may become guilty before God. 20Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin. Romans 3:19-20NKJV
