In The Case For Faith, Lee Strobel records a dialogue between himself and author/philosopher Peter Kreeft:

"How can a mere finite human be sure that infinite wisdom would not tolerate certain short-range evils in order for more long-range good that we cannnot foresee?" [Kreeft] asked.

I could see his point but needed an example. "Elaborate a bit," I prodded.

Dr. Kreeft (a philosophy professor for 38 years) thought a moment. "Look at it this way," he said. "Imagine a bear in a trap and a hunter who, out of sympathy, wants to liberate him. He tries to win the bear's confidence, but he can't do it, so he has to shoot the bear full of drugs. The bear, however, thinks this is an attack and that the hunter is trying to kill him. He doesn't realize this is being done out of compassion.

"Then, in order to get the bear out of the trap, the hunter has to push him further into the trap to release the tension on the spring. If the bear were semiconscious at that point, he would be even more convinced that the hunter was his enemy out to cause him suffering and pain. But the bear would be wrong because his understanding is too limited."

Kreeft let the illustration soak in for a moment. "Now," he concluded, "how can anyone be certain that's not an analogy between us and God? I believe God does the same to us sometimes, and we can't comprehend why he does it any more than the bear can understand the motivations of the hunter. As the bear could have trusted the hunter, so we can trust God."
