A good reason not to believe in God

[Ryft]

What definition do you prefer?

One that accords with the attributes of God (such as omnipresence)—but only if you want the argument to have any bearing on this omniscient God. (For example, see God, Revelation, and Authority by Carl Henry, and especially Eternal God: A Study of God Without Time by Paul Helm.)

Let's be careful here. Are you saying that God exists in one state of affairs eternally? If that is the case, how do you propose his thoughts work? After all, thought is a process and, common to all process, there is necessarily more than one state of affairs.

First, I am saying that God exists in all states of affairs eternally; that is, there is never a state of affairs that escapes God's existence. He describes himself as "the alpha and omega" (the first and last letters of the Greek alphabet), such that God is before everything else and he is after everything else (from which all things exist and for which all things exists). In fact, his omnipresence has a great deal to do with his omniscience; thus by separating them one risks constructing a weak straw man.

The temporal issue is really a sideline here. I don't think it's overly important.

According to your argument it is crucially important, such that you posit an omniscient deity with complete knowledge about all things from t0. Your argument works for a temporally bounded omniscient deity, but that leaves the God of Christianity out of the analysis.

It is not as though God knows in sum "the position and momentum of every particle in the universe at every moment of time throughout existence" at the initial t0.

So he doesn't have knowledge of everything?

Of course he does. That is what omniscient means. Read what I said again and notice what my objection is predicated on. "God exists in all states of affairs eternally ... his omnipresence has a great deal to do with his omniscience." In other words, God knows in sum the position and momentum of every particle in the universe at every moment of time throughout existence at tn (which obviously includes the initial t0).
