1What I am saying is that as long as an heir is underage, he is no different from a slave, although he owns the whole estate. 2The heir is subject to guardians and trustees until the time set by his father. 3So also, when we were underage, we were in slavery under the elemental spiritual forces of the world. 4But when the set time had fully come, God sent his Son, born of a woman, born under the law, 5to redeem those under the law, that we might receive adoption to sonship. 6Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba, Father.” 7So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.
At this point I don't even know what you're arguing for or against. Show me where I changed God's word? You don't see that we can not simultaneously be filled with the Spirit and blaspheme the Spirit?
In Acts 7:51, Stephen to the Pharisees, "You stiff-necked and uncircumcised in heart and ears! You always resist the Holy Spirit; as your fathers did, so do you.” In a nutshell, the unpardonable sin is a sin that a person doesn’t want to give up, confess, or even ask forgiveness for and additionally doesn’t want to hear any more about it from the Holy Spirit. If a person still desires forgiveness and confesses their sins, any sin will be forgiven and blotted out. If he finally and totally rejects the Spirit once and for all, he can't be forgiven because he doesn't want to be forgiven.
The Scribes to who Jesus was speaking were crediting the Spirit's work to Satan. I maintain that it's impossible for a believer to do that. The reason they could not be forgiven is because they were deliberately rejecting the Spirit of God. That's how hard their hearts were.
God can't forgive the one who refuses to hear the Spirit. So, essentially, the sin of blaspheming the Spirit and the sin of unbelief are the same.
