Mark 3:29“but he who blasphemes (present tense) against the Holy Spirit never has forgiveness but is subject to eternal condemnation “It does not state that the one who “blasphemed” (past tense) the Spirit never has forgiveness.
At one time, we all blasphemed the Spirit because we all hated the Word of God...until we came into the faith and start growing to love the Word of God. Do you see the difference?
Reader pay attention
It is the one who is actively and currently engaged in disobeying the Word of God, habitually, without care or concern, without love for the Word, that does not have forgiveness. Thus, if you love the Word of God, and have a desire to practice the Word of God, then you are not blaspheming or despising the Spirit of God...because it is the Spirit of God that is the desire in our heart to go after His Torah. There is a difference between currently being unrepentant and blaspheming the Spirit or hating the Word of God....that person never has forgiveness....and then the person that blasphemed the Spirit and repented, and loves to walk in His Torah just as our Messiah taught and practiced...it is he that has forgiveness.
Make no mistake, God will allow you to defy and disobey Him. He will allow you to follow the crowd and the traditions of men. He will allow you to sin. But He also says there is a day of reckoning coming. As you sow, so shall you reap! “Therefore, to him who knows to do good and does not do it, to him it is sin.” James 4:17
4For it is impossible to bring back to repentance those who were once enlightened—those who have experienced the good things of heaven and shared in the Holy Spirit, 5who have tasted the goodness of the word of God and the power of the age to come— 6and who then turn away from God. It is impossible to bring such people back to repentance; by rejecting the Son of God, they themselves are nailing him to the cross once again and holding him up to public shame Hebrew 6:4 5Those who are dominated by the sinful nature think about sinful things, but those who are controlled by the Holy Spirit think about things that please the Spirit. 6So letting your sinful nature control your mind leads to death. But letting the Spirit control your mind leads to life and peace. 7For the sinful nature is always hostile to God. It never did obey God’s laws, and it never will. 8That’s why those who are still under the control of their sinful nature can never please God. Romans 8:7 The one who belongs listens and responds to Yehovah words. If you don't listen and respond, it is because you don't belong to Yehovah." John 8:47
