God is our all forgiving and merciful Father Who is abounding in love and grace. To every one who repents and seeks forgiveness He is gracious to forgive. Then why would He not forgive the sin of blasphemy against the Holy Spirit?
Now to understand what the sin against the Holy Spirit is, we must first know and understand Who the Holy Spirit is. He is a Person.
His distinctive characteristics are:-
1) Knowledge - He Knows the secrets of God and reveals them to us.
1 Corinthians 2:10-11 NLT
But it was to us that God revealed these things by his Spirit. For his Spirit searches out everything and shows us God's deep secrets. [11] No one can know a person's thoughts except that person's own spirit, and no one can know God's thoughts except God's own Spirit.
2) Will - He Decides.
1 Corinthians 12:11 NLT
It is the one and only Spirit who distributes all these gifts. He alone decides which gift each person should have.
3) Emotions - He Pleads for us.
Romans 8: 26 - 27NLT
And the Holy Spirit helps us in our weakness. For example, we don't know what God wants us to pray for. But the Holy Spirit prays for us with groanings that cannot be expressed in words.
And the Father who knows all hearts knows what the Spirit is saying, for the Spirit pleads for us believers in harmony with God's own will.
4) Love - He helps us Love one another.
Romans 15:30 NLT
Dear brothers and sisters, I urge you in the name of our Lord Jesus Christ to join in my struggle by praying to God for me. Do this because of your love for me, given to you by the Holy Spirit.
5) Paraclete, Comforter, Encourager, Advocate - He will never leave us unless we reject Him. He will be with us as our Comforter and Encourager and Guide and will teach us everything and remind us of the Words of Jesus.
John 14:16,26 NLT
And I will ask the Father, and he will give you another Advocate, who will never leave you. [26] But when the Father sends the Advocate as my representative-that is, the Holy Spirit-he will teach you everything and will remind you of everything I have told you.
6) Person of Authority:- He will instruct us what to do and where to go ( when we are close to Him and are listening to His still small voice)
Acts 16:6 NLT
Next Paul and Silas traveled through the area of Phrygia and Galatia, because the Holy Spirit had prevented them from preaching the word in the province of Asia at that time.
7) Person Who appoints people into office - He will appoint each one into the office of what Father God has destined us to do and be (when we are open to hear Him)
Acts 13:2 NLT
One day as these men were worshiping the Lord and fasting, the Holy Spirit said, "Appoint Barnabas and Saul for the special work to which I have called them."
Acts 20:28 NLT
"So guard yourselves and God's people. Feed and shepherd God's flock-his church, purchased with his own blood-over which the Holy Spirit has appointed you as leaders.
The Holy Spirit is a Person and not just a force or power. He is the 3rd Person of God. We cannot ask for more of the Holy Spirit so that we can use Him. He is not a force which we can use. He is not an 'it' but a 'He'! He is the divine Person of infinite majesty, glory, holiness and power, Who is ever willing to dwell in us and ready to use even us, to glorify the Father, if we allow Him. This is so humbling when we consider His greatness and our puny selves.
Now in Matt 12:31-32 Jesus says that every other sin will be forgiven but not the sin against the Holy Spirit. Jesus was referring to the Pharisees who said that He, Jesus drove away evil spirits because He had an unclean spirit in Him. Why is this sin unpardonable? Because the Pharisees who (practised meticulous adherence to their interpretation of the Torah as well as their eschatological views and applied Jewish law to mundane activities in order to sanctify the every-day world and believed in the resurrection after death) were learned in the law of Moses and had knowledge of the scriptures, yet insulted and rejected the Holy Spirit, in Jesus. They refused to acknowledge that the Spirit in Jesus was the Spirit of God.
The Holy Spirit is the third Person of God, the Majestic Spirit, Who comes to every person and gently convicts and prompts him or her to accept Christ Jesus. Thw Holy Spirit in Acts was poured upon all the people who were listening to Peter speak. They were unbelievers at first but when they yielded their hearts to the Holy Spirit He was able to transform them (Acts 2:1-42). He is the Majestic One Who dwells within the believers of Christ, loves us and patiently waits for us to respond to His call, teaches us everything about Jesus and pleads for us to the Father. He convicts us of our sins again and again and waits patiently for us to change.
When we repeatedly reject the Holy Spirit, this Majestic Spirit, the Spirit Who comes from the Father to dwell within us who are mere sinful creatures, and when we refuse to be convicted by Him, we actually slight and insult Him. Continuous rejection of the Holy Spirit hardens our hearts. Our conscience becomes seared. When that happens, sin will no more seem like something wrong but will seem so normal and even 'right' in our eyes. We then will miss all the opportunities given to us by God, to make all wrongs right. We then will be unable to repent, because we have rejected the Holy Spirit. There will be no conviction of sin without the Holy Spirit.
In summary, to sin against the Holy Spirit is to reject the Holy Spirit and to live an unrepentant life (becoming the walking dead- spiritually dead although still alive) and die an unrepentant death. When one dies with a seared concience and an unrepentant, hardened heart, his end will be disastrous. God cannot forgive the sin of blasphemy against the Holy Spirit. No repentance, no forgiveness.
Having said that, in conclusion, I would like to add this:- No one can judge another to say whether he or she has sinned against the Holy Spirit. Only God knows each person's heart. Only God knows each person's motives. God can in His mercy change anyone, anytime and bring him or her to repentance. When we judge others, we are judged with that same measure. Therefore I would urge all believers to sincerely pray for one another so that no one would be lost. Let us look at our own lives, examine our hearts daily, to see if we have offended the Holy Spirit, repent and change and bear the fruit of the Spirit in our daily lives.
"Search me oh God and know my heart; try me and know my anxious thoughts. See if there be some wicked way in me. Lead me in Thy way everlasting."
Psalm 139:23,24.
Help me always remain pliable in Your hands dear Father. Never let my heart grow cold. Holy Spirit come live in me and never let me go. Teach me Your way so that I will bear the fruit of love, joy, peace, patience, kindness, gentleness, faithfulness and self control in my daily life and glorify the Father. Transform me into the likeness of Christ Jesus. I pray this in Jesus' most precious name. Amen!
