Hebrews 10:29 How much severer punishment do you think he will deserve who has trampled underfoot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
Isaiah 63:10 But they rebelled and grieved his Holy Spirit; therefore he turned to be their enemy, and himself fought against them.
Matthew 12:32 And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
Acts 7:51 “You stiff-necked people, uncircumcised in heart and ears, you always resist the Holy Spirit. As your fathers did, so do you.
One reason some people give for not believing in hell is that hell is just too severe a punishment for wrong beliefs. They say, “Isn’t God overreacting just a little bit? Is a good, moral father who tries to live a good and moral life really going to be condemned to an eternity of suffering in the same way as a man who abuses children?” It seems too much that people are going to hell just because they have not believed the right things about Jesus. But when we say that, we really do not understand what a person is doing when he rejects or even neglects the gospel. Look at Hebrews 10:29: “How much severer punishment do you think he will deserve who has trampled underfoot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?” The writer was saying when you reject Jesus Christ, you are treating His death as worthless. They are saying the death of His Son is worthless. When a person says no to the gospel of Jesus Christ, he is saying the blood of God’s own Son has no value. When a person rejects or simply neglects the gospel, that person is continually rejecting the Holy Spirit of God who is moving in his heart to invite themm to accept the gospel.
