I read that blasphemey against the Holy Spirit is an unforgivable sin. Could someone ellaborate or give an example...

that sin is when someone wont listen to God and gets to the point their conscience is so hard they can no longer hear. its to me a seared heart beyond return.

I like this explanation.

What is blasphemy against the Holy Spirit?


Question: I'm worried that I may have committed blasphemy of the Holy Spirit. How can I know if I committed this sin?

Answer:
Jesus said, "Truly I say to you, all sins shall be forgiven the sons of men, and whatever blasphemies they utter; but whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin "-because they were saying, "He has an unclean spirit." (Mark 3:28-30)

The scribes committed blasphemy when they attributed the miracles of Jesus to the devil instead of the Holy Spirit. They accused Jesus of being possessed by the devil and casting out demons by the power of Satan (Mark 3:22).

Some Bible scholars believe that this particular sin could only be committed while Christ was on earth because the scribes said that Jesus was possessed by Satan. They witnessed with their own eyes the perfect Son of God performing miracles by the Spirit of God. In other words, this sin can't be duplicated today simply because Jesus is no longer on earth in His physical body. The reason Jesus gave this warning was "because they were saying, 'He (Jesus) has an unclean spirit.'"

Many people are afraid that they may have committed the unpardonable sin. The scribes were so embittered and hardened of heart that they weren't the least bit concerned about their own spiritual condition. The fact that you are concerned that you may have blasphemed the Holy Spirit is proof that you have NOT committed this sin. A person who could commit the unpardonable sin wouldn't care.

When one will no longer or can no longer hear the Holy Spirit they are doomed. For it is by the Holy Spirit one is led to repentence.
