28 “Truly I say to you, all sins shall be forgiven the sons of men, and whatever blasphemies they utter; 29 but whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin”— 30 because they were saying, “He has an unclean spirit.” Mark 3:28-30 (NASB)
I have been a Christian for many years. Before God saved me when I was 34 years old in January 1986, I had been an unsaved Church member since I had been a child having made a profession of faith when I was 9 years old in 1960….
During all of that time, I am sure I have heard dozens of different teachings on the Unpardonable Sin. What is it? I heard one preacher say that only first century Jews could commit this sin. Is that right? As we can see in the passage above, Mark 3:28-30, the Unpardonable Sin consists of blasphemy against the Holy Spirit. This sin is eternal and those our Lord was referring to had been accusing Him of having an unclean spirit. Take warning all ye reading this. Our Lord is warning us all that this sin will not be forgiven and that means that those guilty of it are condemned to an eternity in Hell. This teaching by our Lord is found in the three Synoptic Gospels, Mark 3:28-30, Luke 12:10, and Matthew 12:31,31. This sin is “Blasphemy against the Spirit.” It is performed by those speaking expressions of the thoughts of the heart (Matthew 12:33-37, cf. Romans 10:9,10). Those committing this sin were opponents of Jesus and His ministry. They claimed that the Power doing the good works among them was not God but Satan.
