'Guilty' in the Bible

Which one of you [has proof and] convicts Me of sin? If I speak truth, why do you not believe Me?

Jesus said to them, “If you were blind [to spiritual things], you would have no sin [and would not be blamed for your unbelief]; but since you claim to have [spiritual] sight, [you have no excuse so] your sin and guilt remain.

If I had not come and spoken to them, they would not have [the guilt of their] sin; but now they have no excuse for their sin.

If I had not done among them the works (attesting miracles) which no one else [ever] did, they would not have [the guilt of their] sin; but now [the fact is that] they have both seen [these works] and have hated Me [and continue to hate Me] and My Father as well.
