“Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. “Anyone who 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 the age to come. (Mat 12:31-32 NKJ)
“There’s nothing done or said that can’t be forgiven. But if you deliberately persist in your slanders against God’s Spirit, you are repudiating the very One who forgives. If you reject the Son of Man out of some misunderstanding, the Holy Spirit can forgive you, but when you reject the Holy Spirit, you’re sawing off the branch on which you’re sitting, severing by your own perversity all connection with the One who forgives. (Mat 12:31-32)
No sin is unforgivable as John tells us, “ If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” (1Jo 1:9 NKJ) That being the case then what is the unforgivable sin. Matthew tells us it is blasphemy against the Holy Spirit. If you’ve ever been concern that you might have done such a thing, let me put your mind at rest by assuring you haven’t. Having that concern and conviction shows that you have an inner conviction to do right. Remember the Holy Spirit convicts us to make the right moral, ethical and legal judgments.
The scribes attributed the work of the Spirit to Satan, thus showing that they had hardened their hearts and were not able to receive the truth. John tells us that, “the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come.” (Joh 16:13 NKJ) To do what the scribes did was as the Message translation puts it, “you’re sawing off the branch on which you’re sitting, severing by your perversity all connection with the One who forgives.”
Be ever hearing, and if you’re not quite sure of something, put it on the shelf until the Holy Spirit reveals the truth. Don’t let dogma or tradition guide you—it just might be wrong.
