Better reasons to quit Christianity

[spockrates]

I don't understand. Why is the fact that freewill necessitates multiple options necessarily a dilemma?

If He knows what you will do in advance, you can't do anything but what He knows. In other words, you can't really choose the apple instead of the orange if He knows you'll choose the orange. But, as is normally thought, free will demands that we be able to choose the apple. However, this is not true in light of Frankfurt's work.

Well, I don't see a dilemma if the one capable of knowing chooses not to know. You know? For example, God could decide that he will know what choices you will have, but he could also decide that he will not know what choices you will actually make. But please tell me what Mr. Frankfurt had to say.
