Is God Omniscient? Get In Line.

A good deal depends on how one goes about knowing anything in order to impute omniscience to God. Does omniscience mean that God merely knows all the possible outcomes of a given state of affairs, and furthermore He knows which of all the possible outcomes will eventually come to be? ( We exclude the possibility that it is by faith that we know that He knows.)

Maybe.
However, this account assumes that we possess a robust means of describing all possible outcomes, otherwise, how would we be able to assert that God knows all the possible outcomes?

However, if we possess such a robust means of describing all possible outcomes of a state of affairs, then it is absolutely necessary that such a precise instrument of language and knowledge cannot be itself mistaken for omniscience, for then we would be omnisicient.

If I assert "God is omniscient", this is equivalent to asserting "I am omniscient". Else, I could not prove the assertion that God is so omniscient.
Of course, it is acceptable that one have faith that God is omniscient, but this jumps outside the area of proof.
