I posted a variation of this last year. However, in light of recent comments from an Arminian brother, I thought it was time for a slight modification.
Imagine the following: A father allows his two-year-old son to go outside to play knowing full well that their house is next to a lake. He also knows that his son has a habit of not listening when told to stay away from the water. Still, this father doesn't want to be the kind of parent that smothers his kid. The little rascal will have to grow up sometime, so he is given great freedom to make his own choices.
Sure enough, as soon as he sets foot outside, the boy heads straight for the water. His father sees this, but does nothing. He just stares out the window and watches. The child steps onto the dock, and still the father looks on.
It isn't until the boy slips and falls into the water that the father rushes to the rescue. But he doesn't jump in after him. He takes a life preserver from the boat that's tied to the dock and tosses it to his son. "Grab it!" he shouts. The boy continues to splash and scream for help. "Grab the life jacket, son! It's all up to you. If you want to be saved, just reach out and take it."
Eventually, the young boy ceases to struggle and sinks below the surface. The life jacket floats where the father threw it. "Son!" he cries. "Can't you hear me? All you have to do is hold on and I can pull you in." No response. The father turns and heads back to the house. Words cannot describe the sadness he feels, but there just wasn't anything he could do. He offered life, but his offer was rejected, and that ultimate act of disobedience resulted in his child's death.
Now, if that really happened, there isn't a single court in the country that would let the father off the hook. At the very least, he would be found criminally negligent for his son's death. But in the minds of most people, the father would be just as guilty as if he had pushed his son into the water in the first place.
Here's the question I have for you Arminians: If a sovereign, loving, all-powerful, all-knowing God, who neither ordains nor causes bad things to happen but allows them to happen according to his permissive will, creates mankind with the foreknowledge that every human will fall into sin, then how could such a God escape responsibility for the pain and suffering of his creatures, much less the eternal damnation of those who don't respond to his free offer of salvation?
I submit that you cannot answer that question without abandoning your own Arminian worldview. You cannot answer it without resorting to the same theological gymnastics you accuse Calvinists of performing. And you certainly cannot answer it if you have a problem conceiving of a truly sovereign God who works all things for his ultimate glory.
