'Sinful' in the Bible

For whoever is ashamed [here and now] of Me and My words in this adulterous and sinful generation, the Son of Man will also be ashamed of him when He comes in the glory of His Father with the holy angels.”

He came back a third time and said to them, “Are you still sleeping and resting? Enough [of that]! The hour has come. Look, the Son of Man is being betrayed into the hands of sinners.
