but whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin “—Mark 3:29
Jesus promised that all sin can be forgiven, however there is one sin that is eternal and that’s “Blasphemy against the Holy Spirit” So what is Blasphemy? The original Greek word is “Blasphemos” meaning to speak evil, slander, or abusive.
Now to first understand this, we need to understand who the Holy Spirit is. We first need to recognize that the Holy Spirit is God, and to reject the Holy Spirit is to reject God. During this story, Jesus was casting out demons by the Holy Spirit. Remember Jesus was fully human and was baptized by the Holy Spirit (Mark 1:10)
The religious leaders accused Jesus of being possessed with a demon spirit instead of the Holy Spirit, this was blasphemy. Especially considering they knew the scriptures about the prophecy of the Messiah (Christ), they witnessed Gods miracles right before their eyes, yet they still denied Jesus.
But Peter said, “Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back some of the price of the land? While it remained unsold, did it not remain your own? And after it was sold, was it not under your control? Why is it that you have conceived this deed in your heart? You have not lied to men but to God.”Acts 5:3-4
A good example is when Ananias and Sapphira lied to Peter and the Holy Spirit about how much money they had. Peter told them they just didn’t lie to him but to God also. The consequences were fatal as the Holy Spirit put them to death immediately.
What happened here? They denied the Holy Spirit, they blasphemed to God. Now this was an extreme example, however I think God did this on purpose to teach us a lesson how serious “Blasphemy against the Holy Spirit” is
But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised. 1 Corinthians 2:14
Why do some people accept the Gospel and some people reject it? Its because without the Holy Spirit we cant understand or accept Christ. Those who reject the Holy Spirit are committing blasphemy and cant be saved. Its only until we accept the testimony from the Holy Spirit regarding Jesus Christ, that we can come to repentance and be saved The Holy Spirit is not a mythical force, he is part of the Triune God. Listen to the Holy Spirit and be drawn to Christ for your salvation, otherwise live in blasphemy and be condemned eternally
