The Unpardonable Sin

"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." (Matthew 12:31-33)
28 "Assuredly, I say to you, all sins will be forgiven the sons of men, and whatever blasphemies they may utter; 29but he who blasphemes against the Holy Spirit never has forgiveness, but is subject to eternal condemnation"-- 30because they said, "He has an unclean spirit." (Mark 3:28-29)
"And anyone who speaks a word against the Son of Man, it will be forgiven him; but to him who blasphemes against the Holy Spirit, it will not be forgiven." (Luke 12:9-11)
So what is that sin that is unpardonable, cannot be forgiven. The fathers of the Church explained that it is the sin of refusing to accept God's plan for salvation. The Lord told Necodimus:  "Jesus answered, "Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God." (John 3:4-6)

The Apostle Saint Paul speaking to the Corinthians said: "Therefore I make known to you that no one speaking by the Spirit of God calls Jesus accursed, and no one can say that Jesus is Lord except by the Holy Spirit."  (1 Corinthians 12:2-4) . We probably are getting confused here because it seems like a paradox to try to reconcile Mark 3:29 and I Corinthians 12:2-4 but it is not.
A person that is an unbeliever will not start by giving honor to the Son of Man (Christ in the flesh), but he might resist him and persecute His way as Paul himself did when he was Saul of Tarsus. But once one believes, he no longer will say any evil against the Son, but in order for the transition to occur, one has to honor the Holy Spirit of God and accept the voice of God in him. Jesus explained to the disciples and Apostles before hand: "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you." (John 14:25-27)
And if one refuses help, he cannot be helped and he/she most certainly will not be able to accept the help because of his resistance. And as was explained before, God does not force his will. We have to accept by our own free will.
So, if one was dead in his sins and curses God, Christ, the Church, and everything else in his sinful state, he still has a chance to be forgiven all that and more, all sins are forgiven, as long as he allows the spirit of God, the Holy Spirit to come in him and change him, but if he resists indefinitely, he looses indefinitely, and that is the sin that is not forgiven on earth or in heaven because that person has refused to allow God to come and be in him.
I did read about a man who committed a serious crime of betraying his country, and was condemned to death by firing squad. The father the priest came to hear his last confession, he confessed to the father the priest his crime for which he was condemned to death by civil authority, he accepted his punishment on earth, and by confessing his sin, he was forgiven by the God of heaven and earth. He also was smart to confess all his other sins and to ask God's forgiveness. When the day of execution came, he and his father of confession the priest both stood on opposite ends of the execution range. The condemned man stood bravely with internal feeling of readiness crying: "Lord Have Mercy on me, Lord Forgive all my sins" and the father the priest also stood there sad but comforted that that person has his sins forgiven because he accepted the will of the Holy Spirit and placed the matter of his redemption in the hands of God. The father the priest continued to recite the words of entreatment of the Holy Spirit asking forgiveness for the brother who confessed all his sins and was ready to meet God in a white as snow, clean as white wool condition.
I also remember with sadness a couple of incidents of suicide, in one incident the person was given a few minutes to live so he can confess the sin of despair and to ask forgiveness from God before he died of the severe burns he inflicted on himself in his despair, that started as blasphemy against the Holy Spirit, but was caught in the last minute by repenting. In the other incident, the person did not have the chance to repent and died in his sin.
An advice I gave to young people in the 30+ years of teaching youth classes, and is most appropriate for all that are in despair, when you have more difficulties than you think you can handle, because despair and loosing hope can lead to blasphemy and the ultimate blasphemy is attempting or committing suicide, because this will be committing the unforgiven sin, blaspheming against the Holy Spirit of God.
Remember always that: "12 Blessed is the man who endures temptation; for when he has been approved, he will receive the crown of life which the Lord has promised to those who love Him. 13Let no one say when he is tempted, "I am tempted by God"; for God cannot be tempted by evil, nor does He Himself tempt anyone. 14But each one is tempted when he is drawn away by his own desires and enticed." (James 1:12-14.) Also "11Indeed we count them blessed who endure. You have heard of the perseverance of Job and seen the end intended by the Lord--that the Lord is very compassionate and merciful." (James 5:11).
In conclusion remember always, that God will not tempt us beyond our ability to endure. Moreover, He promised us saying: "Call upon Me in the day of trouble; I will deliver you, and you shall glorify Me." (Psalm 50:14). Because when we do, we are connected to Him and will not fall in the sin of despair that is the blasphemy against the Holy Spirit. May the Lord protect us all from this undesired state, many are easily drawn into in these days of great tribulations.
Glory Always be to our God. Honor and Glory, Glory and Honor be to the Father, the Son, and the Holy Spirit. One God. Amen.
