Any ideas?

lets go with the fact of deductive logic. ill go first.

If God is all knowing, thus
all events (in relative to common perspective of time)are then predetermined by God, thus
time is predetermined, thus
the act of morality is not based on free will but was already set to be accomplished.
in conclusion: "If" god is all knowing, applying basic logic tells us either moral does not exist due to lack of free will, or it really does not matter at all.
but keep in mind these arguments are founded on human logic, and our understanding of time. should you be able to provide a counter please provide your fundamental understanding of time and logic.

And I came in here assuming you had some....
