I agree, and I think the Holy Spirit and Jesus go hand in hand accomplishing that.
It has been my thought that if you are not compelled by right and wrong, you have already committed the unpardonable sin.
If you ponder right or wrong, you do so because the Holy Spirit is working on you. If it isn’t, you’ve already broken the connection.
IMO, that was the danger of Moral Relativism.
It taught you not to assess good or evil. If it feels good, just do it.
That’s straight out of Satan 101.
Or as Paul tells in Romans, a “private righteousness.”
It’s the sad Garden story. But God let humanity do it, rather than to ever force His love on a single unwilling soul.
It would be unforgivable to reject a Savior. That would be to believe that right and wrong were utterly within one’s own grasp to control, rather than needing a Savior to guide and teach and bestow power on one into. Only this can correct the Garden error.
