'Sinful' in the Bible

Every one, however, who has been ashamed of me and of my teachings in this faithless and sinful age, of him the Son of Man also will be ashamed when He comes in His Father's glory with the holy angels."

A third time He came, and then He said, "Sleep on and rest. Enough! the hour has come. Even now they are betraying the Son of Man into the hands of sinful men.
