Matthew 12:31

¹⁰Everyone who speaks a word against the Son of Man will be forgiven, but those who blaspheme against the Holy Spirit will not be forgiven.

²⁸“Most certainly I tell you, all sins of the descendants of man will be forgiven, including their blasphemies with which they may blaspheme; ²⁹but whoever may blaspheme against the Holy Spirit never has forgiveness, but is subject to eternal condemnation.”³⁰—^[+] because they said, “He has an unclean spirit.”

²⁹How much worse punishment do you think he will be judged worthy of who has trodden under foot the Son of God, and has counted the blood of the covenant with which he was sanctified an unholy thing, and has insulted the Spirit of grace?

²⁶For if we sin willfully after we have received the knowledge of the truth, there remains no more a sacrifice for sins,

⁵¹“You stiff-necked and uncircumcised in heart and ears, you always resist the Holy Spirit! As your fathers did, so you do.

¹³although I used to be a blasphemer, a persecutor, and insolent. However, I obtained mercy because I did it ignorantly in unbelief. ¹⁴The grace of our Lord abounded exceedingly with faith and love which is in Christ Jesus. ¹⁵The saying is faithful and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief.

³¹Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. ³²Whoever speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age, or in that which is to come.

⁴For concerning those who were once enlightened and tasted of the heavenly gift, and were made partakers of the Holy Spirit,

¹⁶If anyone sees his brother sinning a sin not leading to death, he shall ask, and God will give him life for those who sin not leading to death. There is sin leading to death. I don’t say that he should make a request concerning this.

⁹If we confess our sins, he is faithful and righteous to forgive us the sins and to cleanse us from all unrighteousness.
