Romans 3

Paul asks about the advantage of being Jewish if everyone is under sin. He confirms that the Jews still hold a huge advantage because they were entrusted with the oracles of God (the Scriptures). However, Paul concludes his argument by quoting the Old Testament: "There is no one righteous, not even one." He then delivers the heart of the gospel: God declares sinners righteous freely by His grace through the redemption that is in Christ Jesus, who was a propitiation for our sins.
