Is there an unforgivable sin?

Is there an unforgivable sin?
Yes.	No.
Matthew 12:31-32 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come. Mark 3:29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation. Luke 12:10 But unto him that blasphemeth against the Holy Ghost it shall not be forgiven.	Acts 13:39 And by him all that believe are justified from all things.
