According to Hebrews 10:26, to sin willfully means to continue to sin willfully, as the form of the Greek verb indicates. The reference here is not to single acts of sin committed in the full knowledge of their evil character, but to the attitude of mind that dominates when a person deliberately refuses salvation, and rejects the Holy Spirit. This is deliberate, persistent, defiant sin. It is a considered reversal of the former decision to accept salvation in Christ and to yield one’s heart and life to Him. It is premeditated decision to leave the Lord.
Christ, in Matthew 12:31, spoke of the unpardonable sin. He referred to a group of Pharisees that had attributed the power of the Holy Spirit (v. 28) to the devil (v. 24) in the full knowledge that their charge was false. It was this deliberate rejection of light that was leading them, step by step, toward “blasphemy against the Holy Ghost.” It is important to note that the statement made by the Pharisees came as the climax of a protracted process of rejecting increasingly clear evidence of divinity of Jesus, a process that had begun with the birth of Jesus but which became more intense as His ministry progressed.
Blasphemy against the Holy Spirit, or the unpardonable sin, consists of progressive resistance to truth that culminates in a final and irrevocable decision against it, deliberately made in the full knowledge that by so doing one is choosing to pursue his own course of action in opposition to the divine will.
So, a person troubled with a haunting fear that he has committed the “unpardonable sin,” thereby has conclusive evidence that he has not committed it.
A person whose conscience troubles him may solve the problem and remove the tension in one of two ways: He may yield to the transforming power of the Holy Spirit, and respond to the promptings of the Holy Spirit by making wrongs right with God and man, or he may sear his conscience and eliminate its painful promptings by silencing the Holy Spirit (Ephesians 4:30).
The person who takes the latter course cannot repent, because his conscience has been forever made insensitive, and he does not want to repent. He has deliberately placed his soul beyond the reach of divine grace. His persistent perversion of the power of choice results in the loss of the power to discern between good and evil. Evil finally appears to be good, and good appears to be evil (Micah 3:2; Isaiah 5:20).
In His service,
