Still does nothing to show God's will always is carried out in man.
God's will is always carried out in all creation. Certainly, his will is done through a process.
God's will was that you were born from your mother. Right? But it took nine months of pregnancy and a delicate embryological process for the will of God to be accomplished in you and your mother.
God's will in human heart to make him a citizen of his Kingdom may take many years, and will follow a process that
respects the free will of His creature. But how would we even think that God's purpose will be frustrated?
CALVIN'S RATIONALE
To the problem of how evil people can defy God's Power and choose to resist him, Calvin offered this "solution": People go to hell not because God's will has failed, but because God's will, since the very start, was to let those people go to hell. So, God really doesn't feel "sorry" when He sees million of his creatures screaming in pain among the eternal flames.
At first sight (leaving aside for a while the disturbing element of eternal torture), there is some internal consistency in Calvinist rationale.
For example: God killed all dinosaurs not because something failed in his plan, but because He wanted only certain animals, not all of them, to survive and evolve. So God chose the small mammals which would survive the asteroid, and let the dinosaurs go extinct.
In the same way, Calvinist think, God's will is that you are saved, and I am not. I'm like one of those dinosaurs. If I go extinct, well... that was part of the plan.
THE ANTIDOTE TO CALVIN'S RATIONALE
The only valid argument against Calvinism, in my opinion, is to think that God WANTS to save us all, and that God's plan includes that certain people resist him FOR A WHILE, in order to accomplish certain things for others and ourselves.
That's how Paul explained the resistance of Israelites to accept Jesus. God had put on them a "veil" or produced a "hardening" of their hearts, so that Gentiles could profit. But in the end, God would save all Israel. (Romans 11:11-27)
From your perspective, you could also apply Paul's thinking about Jews and extend it to other people.
For example, you could think:
"It is within God's plan that Pancho Frijoles remains with a veil in front of his eyes, a hardening in his heart, so that we can profit from debates he triggers in this Forum and we can develop more skills to defend Christianism. Once God's purpose with Pancho Frijoles has been met, God will lift the veil, soften his heart and attract Pancho to Him."
If we all thought that way, we would be kinder to each other in this Forum, thinking that whatever the mental "veils" or "hardenings" our brothers and sisters may have, God will end up lifting those veils on due time.
