8 Bible Verses about The Unpardonable Sin

Therefore I tell you, people will be forgiven of every sin and abusive word spoken [against God]. But abusive words spoken against the Holy Spirit will not be forgiven. And whoever speaks an [abusive] word against the Son of man will be forgiven [of it], but whoever speaks [an abusive word] against the Holy Spirit will not be forgiven [of it], not in this world nor the one to come.

But the person who speaks against the Holy Spirit can never be forgiven, for he is guilty of a never ending sin."

But Peter said to Ananias, "Why has Satan filled your heart [causing you] to deceive the Holy Spirit by keeping back part of the selling price of the land [while representing it as the full price]?

You people are unbending and unrepentant in your hearts and [unwilling to listen with] your ears. You are always resisting [the desires of] the Holy Spirit just like your forefathers did.

And do not grieve God's Holy Spirit by whom you were sealed [i.e., given evidence of God's ownership] until the day of redemption [i.e., until you receive your new body in heaven. See 1:14].

Do not squelch the [influence of the] Holy Spirit [in your lives].

How much more severely do you think a person deserves to be punished who has trampled on the Son of God and has regarded the blood of the [New] Agreement, with which he was set apart for God, an unholy thing and has insulted the Holy Spirit, through whom God's unearned favor is shown?

If anyone [of you] observes his brother [or sister] sinning [in a way that would not lead] to [spiritual] death, he should ask [God, in prayer, to help that person], and God will give him [spiritual] life, [that is], to such ones, provided their sin is not leading to [spiritual] death. There is such a sin that leads to [spiritual] death. [See Heb. 6:4-6; I Tim. 5:6; Heb. 10:26-27; II Pet. 2:20-22]. I am not suggesting that you should ask [God, in prayer] about such a situation.
