Blasphemy against the Holy Ghost is simply this, coming straight from the narrative, knowingly and brazenly attributing the clear and unmistakable display of the power and authority of the Third Person of the Trinity to the Devil.
Do that to the First Person. You can be forgiven. Do that to the Second Person. You can be forgiven. Do that to the Third Person, and you've crossed the line. You see, there is rank in the Godhead. But what is also revealed to us about the ways of God is, that the first shall be last, and the last shall be first.
So in the recording, the preacher spends 10 or 12 minutes trying to tell us that the blasphemy against the Holy Ghost is impossible to commit, really, for anyone. It's just another way of Christ saying you're either for or against Me. So the unforgiveable sin doesn't really exist.
But I disagree. We have an account of it right there. He casts out devils by Beelzebub, the prince of devils.
This was not the sin of Hyles or Schaap.
