Blasphemy against the Spirit is a concept mentioned in the Gospels of Matthew and Mark. It is the sin of attributing to Satan what is the work of the Spirit of God, such as when the Pharisees accused Jesus of driving out demons only by the power of Beelzebul, the prince of demons. Blasphemy against the Spirit is conscious and hardened opposition to the truth, "because the Spirit is truth". It is ongoing hardening of the heart against the Holy Spirit who is trying to lead one to repent of sin and believe in Christ. It is an issue of the heart that manifests in one’s words and actions. The sin of blasphemy against the Spirit cannot be forgiven since one who does not acknowledge their sin does not seek to have it forgiven. It is essentially the sin of rejecting Christ. Blasphemy against the Holy Spirit has to do with accusing Jesus Christ of being demon-possessed instead of Spirit-filled. It is not a wayward word uttered in a moment of anger, nor is it some other dramatic sin like murder, suicide, or adultery. Rather, it is a persistent rejection of the convicting work of the Spirit, whose job it is to expose our sin and lead us to accept Christ. Any sin that a person clings to by continually resisting the convicting power of the Holy Spirit is blasphemy against the Holy Spirit. There is not one specific sin that is unforgivable, but rather a perpetual hardening of the heart and willfully sinning against God and man. The unpardonable sin is any sin that a person doesn’t want to give up, confess, or even ask forgiveness for and additionally doesn’t want to hear any more about it from the Holy Spirit.
