As a Calvarminian, I sleep extra nice. The Augustinian (Calvinist) perspective informs me it is all up to God, and the Arminian that God ultimately gives everyone exactly what they want.
As an agnostic, I had decided that if there were a God, It would be beyond my ability to fully comprehend. Thus such doctrines as the Trinity, or Sovereignty, never raised a problem for me. Rather it were the many other understandable and logical gods of the various religions and philosophies that I found suspiciously shallow.
Reading the Bible I met the kind of complex "wrinkled" texture that reality has. That stubborness to be fully accounted for, not altogether irrational, but just on the other edge of logic. While that in itself did not convince me to become a Christian, it definitely impressed me. The Christian God is still the only one I can not fully understand. To me it has always seemed highly irrational to presupose God is subject to rules of logic that are nowhere mentioned in Scripture, and which do not serve to fully account for nature.
So yes, following any one perspective to it's "logical conclusion" will lead one to a stark dilemma: a capricious God or an impotent God. However, where praytell IN SCRIPTURE (not in the Renaissance musings of Erasmus or Calvin) does it say that God is bound by our particular brand of "logic?"
I know there are many who disagree with this, but I truly believe that human reason is an idol among us Presbys. God is God, and His very manner of thinking is not our manner of thinking. What rules He applies to Himself are not dictated by some human philosophical system of reason, no matter how useful or pretty. If that means a God who will almost, but never quite, fit into a systematics, so be it.
In God "Justice and Mercy kiss," and "ALL things are possible with God." So we have a real choice, and our prayers (or lack of them) a real effect. Yet it is also true all is His choice, and none ours.
So in one sense, I guess I am a super-duper Calvinist. I not only affirm God's Sovereignty of action, but God's Sovereignty of thought. He says we have a choice. He says we do not. Both are then true, and so "logic" does not bind nor explain Him. I am utterly dependent, more so than the typical Calvinist that thinks He can box God with a cute acronym. He is the Lily of the field, not the TULIP of the well-manicured human garden.
Yet I do not regret the loss of my mind. I had already lost that during theoretical math, Einsteinian relativity (where considerations of perspective force paradoxically true conclusions), and whatever shred of reason I had left Quantum Mechanics had long ago made a mockery of. So if the quaint system of logic can't even cope with the natural, how do we suppose it can chain God?
Reason is a good, heathy staple. It tastes better with a dash of mystery. Does not the Scriptures read to you this way? A solidly reasonable (if miraculous) historical account with an occasional zinger of a Nephilim that dosen't quite fit?
Of course, to have as the main course the spice of mystery, with a dash of reason is not healthy at all, as trying to eat an ounce of steak among a pound of spices. For the most part the Scriptures are very reasonable, logical fare. But on occasion Scripture gives us something, like the Trinity, especially that part where God cries out in quote of the Psalmist "My God, My God, why have You forsaken Me?" that is just beyond our comprehension.
And so I sleep quite soundly. Knowing what I do, and fail to do, really does matter; but that God has it all worked out on His end as well. I get my cake and eat it too.
How Satan must twist in anger at how unfair God is. It's like playing chess with a grandmaster. Even though you may know all the rules, you are mated by the third move, and don't even know it.
