I should have counted how many times Paul just including chapters 1 through 3, has said that there are none righteous. There is no one who has not sinned. He wants to make it very plain that everyone is guilty. Romans 6:23 says the wages of sin is death (I just want that one clause) which tells us that if all are guilty of sin, if everyone has sinned, then they are all under the sentence of death. Them's the truth. That is reality.
