The omni's go hand in hand. To deny one essentially denies them all. Scripture tells us God is Almighty (omnipotent). Since this is true, whatever He wills to pass necessarily must. So, His omnipotence insures omniscience, for nothing can happen apart from His power and will (understand I'm infra when I state this). Omnipresence is a scriptural given as well, though
Enyart denies it.
And, if He sees everything, then He also knows everything, and with omnipotence, no future action is without His knowledge for "in Him, we live and move and have our being" and "without Him we can do nothing."
Is it 2011 for God or is it that He is relational to us in 2011? Is it really 2011 for a God with an eternal past or 2011Xa billion? No. It is not 2011 or even 2trillion for God. It is 2011 A.D. from a randomly chosen point in time. It is not 2011 for God yet He relates to us in our 2011. It is our's, not His. Why is it this difficult to wrap your head around the fact that God has no beginning therefore it is impossible for sequence? I said this before,
God's past isn't over, it cannot be else He is a creation as you and I.
Once you wrap your head around this fact, any assertion of duration like unto our own is sheer nonsense. Yes, He relates to us in our durative reality, no, it cannot possibly be the only reality for Him. Its impossible.
