Blasphemy against the Holy Spirit is a total and continuous rejection of God and is the only sin that cannot be forgiven. Whoever blasphemes against the Holy Spirit rejects him completely, never reaching repentance.
Jesus said that all sins will be forgiven, except blasphemy against the Holy Spirit ( Mark 3: 28-29 ). The Bible does not say exactly what blasphemy against the Holy Spirit is, but we can understand what it means from the context.
The Pharisees had accused Jesus of casting out demons by the power of Beelzebub, the prince of the demons. Jesus explained to them that this was ridiculous, because Satan does not work against himself. Jesus also warned that there are only two sides: whoever is not with him is against him ( Matthew 12: 30-31 ). Then he said that all sin, except blasphemy against the Holy Spirit, would be forgiven .

Against all evidence, the Pharisees were rejecting Jesus. But Jesus said that even that could be forgiven. The real danger is to reject the Holy Spirit.
The Holy Spirit’s job is to convict sin and lead to repentance. To be saved, a person must repent of his sins ( John 16: 7-8 ; Acts of the Apostles 3: 19-20 ). Therefore, anyone who blasphemes against the Holy Spirit cannot be forgiven because he rejects the Spirit’s conviction and repentance. Rejecting repentance is blasphemy because it insults God , who gave everything to bring salvation and deliverance from sin.
