I would pay any price to be able to say truthfully "All will be saved." But my reason retorts, "Without their will, or with it?" If I say "Without their will" I at once perceive a contradiction; how can the supreme voluntary act of self-surrender be involuntary If I say "With their will," my reason replies "How if they will not give in?"
I'll tell you how. God knocks them over the head with irresistible grace, and changes their desires. Then they are going to want to commit that act of self-surrender, with perfect compatibilist freedom. But since God can do that for everybody, he will, and therefore universalism is surely true. No?
