Not at all disagreeable (except that you're disagreeing :tongue3
, and perhaps it does seem circular. Let me try to explain further.
I have no ability to fly or to walk on the ceiling. That is not my fault; it's the way I was born. It would be unfair for anyone to blame me for that inability.
However, one meets drunks, drug addicts, wife-beaters, homosexuals who will say, "I can't help it; it's just the way I am." But we do not (or should not) say to them, "Oh, fair enough then," and leave them to it. We tell them to repent and turn away from their sinful ways.
So it is with all men. They are slaves to sin by their own fault and wickedness, but they will not repent and turn to Christ, not because God is preventing them, but because they are in love with their sin and do not want to change They prefer darkness to light.
This is the understanding of Jonathan Edwards, Andrew Fuller, Spurgeon and others, and indeed, the Holy Spirit speaking through Paul (Romans 2:5). It's not something I made up.
