Blaspheming the Holy Ghost
The one single sin for which there is no forgiveness is the Blasphemy of the Holy Ghost. Jesus Himself Made this plain declaration. "Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:" (St. Mark 3: 28-29) It is sad that very few souls in the church have any understand what blasphemy of the Holy Ghost represents. You may ask how to know when and where this happens. That the danger, there is a line in the sand of time that to cross over and its to late. We must learn to fear God and serve Him in utter Devotion.
