Well its speaking against the Holy spirit, and its considered and unforgiveable sin. I know that God knew what he was doing when he decided it was speaking against the Holy Spirit, many people speak against God, even use his name in curses and as profanity. Sometimes when I attend movies or watch television even if its a talk show host or in a movie, with all the things someone could use in profanity its amazing to me that they would use the name of Jesus as a swear word, or God, but its like so often done its automatic, and if the scripts are written its evidence of what the bible says that we war not against flesh and Blood but against spiritual wickedness in high places. When I hear this I automatically pray, its even been found that in a lot of movies that are dealing with subjects, of demons or witchcraft that they hire actual staff to come in to use real curses, or to use the actual summons of evil angels or demons. Why would anyone want to do this in a crowded theatre, if I am in the audience then I Began to pray. Lately I have to be very selective of what movies, and even television shows I watch. There is no longer what seems like a family hour or time frame that the shows are family friendly, even the cartoons are dealing with subjects that do not uplift or bless the lives of families.
God knew our hearts and minds an so he devised a way, that not many would have commited this unforgiveable sin of speaking against the Holy Spirit, never heard someone use that term as a curse word or in a profane manner. This allows many who might have violated this sin, if blasphemy was against the name of God, or the name of JESUS CHRIST, to still have the opportunity to enter the kingdom of God. Some have turned against Christ, and still returned some have done vile things and said things against God which they have repented of an still have a chance of having Their souls saved. Although many even speak against the bible and the word of God which is confirmed in often three or more places scripture says. They still do not speak about the part of the trinity that has guided the prophets and the writers of the word of God. The bible says his word will endure forever. Many have left this world who have attacked the words written in the bible but still the bible is listed as one of the best selling manuscripts. Many are still organizing new translations, myself I Still rely on the King JAMES HOLY BIBLE. It is the translation that most other languages are closest to.
So just remember to Bless God that he cares for us, that he is mindful of us, and knowing that we are leaning toward sin, he has made away for us and he cares for us, and has shown us great MERCY AND GRACE, Because he has made it hard for the average person to commit Blasphemy. I THANK YOU GOD. FOR YOUR TENDERMERCIES.
