Wrong, if there is breath there is hope. God is on the mercy seat now. Repent and it could be changed around. You could either enter into the gates of heaven with your sins in front of you, covered by the blood of Christ or behind you to be judged. It is always our choice. That scripture was to show them that said He did His miracles by the power of satan that they could not believe Him but that they were to believe the works. You cant blaspheme the Holy Ghost if you don't know what it is. Once you encounter it and are filled life changes, every doubt and concern and unbelief vanish. God bless
