Hmmm...You're changing definitons midstream. The three attributes are A - Omnipotence, B - Omniscience, and C - Omnipresence, according to your first sentence. A is the basis for the other two. C is not directly dependent on B, but it is a function of A. B is a logical result of A, because how can it be that God would create something He doesn't know? If A is not true, neither B or C can be true. If B and C are true, then A must be true. If B is true, then A and C must be true. In short, if God is not Omnipotent, then He cannot be Omniscient or Omnipresent.
God can Foreappoint on the basis of A, and His Word specifically says He does not Foreappoint on the basis of B. Foreappointment is not a function of C, nor is C dependent on it.
It seems you're saying that God can have absolute Foreknowledge, (B), but not be able to do anything about it (Not A). Of what possible benefit could that be to anyone? If that is so, then this world is a random accident, and we have no basis for hope in anything.
Actually, what I've said is that A, B, and C are all independent of one another.
I would think that someone totally knowledgeable would be quite an asset EVEN IF he couldn't pick up a 2 pound weight.
