All sins are pardonable, EXCEPT ONE.

Jesus said, "And so I tell you, every sin and blasphemy will be forgiven men,                                                                          but the blasphemy against the Spirit will NOT be forgiven. (Matthew 12:31).

Anyone who speaks a word against the Son of Man [Jesus] (Matthew 9:6; Luke 6:5) will be forgiven,                                 but anyone who speaks against the Holy Spirit will NOT be forgiven, either in this age or in the age to come.        (Matthew 12:32).
