Only one sin is put forward by Jesus as being unforgivable.
Matthew 12:22-32, ESV
22 Then a demon-oppressed man who was blind and mute was brought to him, and he healed him, so that the man spoke and saw. 23 And all the people were amazed, and said, “Can this be the Son of David?” 24 But when the Pharisees heard it, they said, “It is only by Beelzebul, the prince of demons, that this man casts out demons.” 25 Knowing their thoughts, he said to them, “Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand. 26 And if Satan casts out Satan, he is divided against himself. How then will his kingdom stand? 27 And if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore they will be your judges. 28 But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you. 29 Or how can someone enter a strong man’s house an
d plunder his goods, unless he first binds the strong man? Then indeed he may plunder his house. 30 Whoever is not with me is against me, and whoever does not gather with me scatters. 31 Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven. 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.
The sin that won’t be forgiven is blasphemy against the Holy Spirit, and if the context which prompted this statement from Jesus is an example of this sin, then it has to do with attributing to the devil the works of the Holy Spirit.
Ok. Don’t freak out over this (some people do). I hold to the old adage that if you have committed the “unpardonable sin,” as it has been called, then you wouldn’t really care whether you have committed it. In other words, if you are concerned
about your relationship with God, you have not committed this sin.
If this is true (and it is) then there must be a path back into a right relationship with God no matter what else we have done. End of discussion. The problem is not that God isn’t there for us and available but that we have hardened our hearts because of sin, bitterness, anger, hurt, etc. This is a dangerous place in which to find ourselves, but not impossible. The writer of Hebrews stressed this urgency:
7 Therefore, as the Holy Spirit says, “Today, if you hear his voice, 8 do not harden your hearts (Hebrews 3:7-8a, ESV).
You might be worried about this and be saying to yourself, “But I am afraid my heart is too hardened.” If you are saying this then you heart is not completely hardened, which is evidence that the Holy Spirit is drawing you still.
What to do?
Only God in His mercy and grace can restore you to a right relationship with Himself. The good news is that He wants to! The story of the Prodigal Son is a picture of God’s heart (Luke 15) and in John 14:9 Jesus said “If you have seen Me you have seen the Father.”
Here’s what you can do today to move towards God again:
Reaffirm your acknowledgement of His Lordship. Don’t get tangled up in those words. Do you believe Jesus Christ is God? Are you willing for Him to be your Lord? Then reaffirm this in prayer. Talk to God from your heart.
Embrace again His resurrection. He is alive and because of this He has the power to make you alive again!
Call on His Name. Just cry out to Him from your heart.
Take in His Word again. Put aside the questions you have about inconsistencies, etc. There will be time for that later. The gospel of Jesus Christ is the power of God for salvation. Hear it again!
Pray a “whatever it takes” prayer. “O God, whatever it takes, rescue me! Bring my heart and my mind back into complete compliance with Your will!”
