In chapter 3 of the Gospel of Mark, we read,"The teachers of the law who came down from Jerusalem said, “He is possessed by Beelzebul! By the prince of demons he is driving out demons.” So Jesus called them over to him and began to speak to them in parables: “How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand. If a house is divided against itself, that house cannot stand. And if Satan opposes himself and is divided, he cannot stand; his end has come. In fact, no one can enter a strong man’s house without first tying him up. Then he can plunder the strong man’s house. Truly I tell you, people can be forgiven all their sins and every slander they utter, but whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin.” He said this because they were saying, “He has an impure spirit.” —Mark 3:22-30
In this passage, Jesus not only explains how someone can blaspheme the Holy Spirit, but also goes on and declares that this type of blasphemy will never be forgiven for it is an eternal sin. Unfortunately, there are many religious people today who tend to attribute the works of the Holy Spirit to demons. Charismatic and Pentecostal churches are constantly under attack today by certain religious groups and the miracles that take place in these congregations are attributed to demons. Whether these people are guilty of an eternal sin or not is God's job to judge, but from the above passage, we can conclude that what they do, at least appears to be a good example of blaspheming the Holy Spirit. There are also atheists who tend to participate in a challenge where they blaspheme the Holy Spirit in a YouTube video in order to buy a ticket to Hell; even though given the criteria and the explanation in this passage, what they do is ignorant and does not really appear to be a blasphemy against the Holy Spirit, their willingness to blaspheme the Holy Spirit and go to Hell alarms the bell that they may have been given over to a reprobate mind.
When Jesus was on the Cross, one of the things that He said was, "Father, forgive them for they know not what they do." Luke 23:34. Could blasphemy against the Holy Spirit be forgiven because the person who has done it has done so ignorantly? I would say yes it's possible in my opinion. After all, we can't really compare the miracles that Jesus performed with 100% success rate to the miracles that are taking place today. Having said that, blaspheming the Holy Spirit is a serious sin as warned in scriptures, and it would not be a wise thing to attribute someone's miraculous testimony to Satan and demons, no matter how skeptic you are. Proverbs 18:21 tells us that the tongue has the power of life and death, so if you're not sure whether someone's miraculous testimony is true or not, remain skeptic, and do not attribute it to demons, and ask yourself the question that Jesus asked, which is how can Satan drive out Satan!
