MAT 12:31

31 You [are saying that it is not the Holy Spirit who is enabling me to expel demons]. So I will say this to you: [If] those who offend and slander other people in any way are [then sorry and ask God to forgive them, God] will forgive them. But people who discredit what the Holy Spirit does will not be forgiven {[God] will not forgive [people] who discredit what the Holy Spirit does}.
