One of our Pelagian heretics very recently claimed that Jesus said only those who choose to sin are slaves of sin. But that person intentionally added to Scripture, trying to make a ridiculous point, which basically amounted to, Scripture does not mean what it says. It came across as they want to believe and want others to believe that only atheists wilfully sin, because they say so, although that is not what Scripture says, nor is it what Jesus said. He said everyone who sins is a slave to sin. That we were slaves to sin before being set free by Jesus is repeated throughout Scripture in a number of places. All sin. People make up all kinds of things that are not in the Bible trying to prop up their man made traditions and vain philosophies of man. They are effectively denying the work of the Holy Spirit of God because that is how Scripture was written. They become so invested in their viewpoint that it is nothing to them to fabricate things, bear false witness, and say things that border on blaspheming God, such as saying He raped Mary. Another has repeatedly told us that God is unfair. They mutually agree on the idea that God is an unjust tyrannical monster kidnapping people against their will if He acts unilaterally. But in the final analysis denying the work of the Holy Spirit of God is largely understood as rejecting God, of denying that He sent His Son to save His people from the wages of sin. All other sins are paid for, but if you do not believe in the atoning death of Jesus Christ which paid the sin debt through the shedding of His righteous blood, and subsequent resurrection of our Lord, you will suffer the second death which is everlasting.I might be wrong, but I think blasphemy has to be intentional. Intentional irreverent words. I think one can "blaspheme against the Holy Spirit" today in that they can say something blasphemous against the Holy Spirit, but Jesus is talking about the specific sin he saw them commit given the context.
Matthew 12:32 King James Version
32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
People were seeing Jesus do miracles through the Holy Spirit, and some blasphemed against the Holy Spirit after seeing the Holy Spirit at work. Unforgivable according to Jesus.
People get this sin wrong all the time and there is a lot of confusion about it.
Romans 3:21-25a ~ Apart from the law, righteousness from God comes through faith in Jesus Christ to all who believe. There is no distinction, for all have sinned and fall short of the glory of God, and are justified freely by His grace through the redemption that is in Christ Jesus. God presented Him as the atoning sacrifice through faith in His blood.
