IOW, God sees the decisions you make from all time and He predestines it based on what He knows you will do. God does NOT predestine you capriciously.
God does not do anything arbitrarily or capriciously I agree – however, I reject the idea of foreseen faith as forming the basis for election.
The idea that omniscient foreknowledge can precede providence is, as both Calvin and Augustine explained, rather absurd from a logical perspective (no disrespect to your view since a year ago I would have agreed with you).
It winds up saying God only does what He knows He is going to do because He knows He’s going to do it (try saying that ten times

).
In other words God becomes a prisoner of His own knowledge. There’s a variety of theories on this, including some pretty interesting ones on the Catholic side (perhaps the most elaborate is Molinism, which many protestants agree with, authored by the 16th century Jesuit Luis Molina of Spain).
However, after examining all of these soteriological theories and matching them against both scripture and logic I must firmly agree with Calvin.
The idea Molina presented is that God has knowledge of counterfactuals. The roots of this theory can perhaps be traced back to Aquinas who wrote (in Summa Theologica) that God not only knows what will be, but what can be.
Molina tried to create a doctrine that both preserves free will and divine providence and foreknowledge (which can have logical tension with one another). He imagined that God surveys different possible worlds to see what our decision would be in each of them and elected accordingly. This theory actually attracted me for some time, until thinking about it more deeply.
In each of these different worlds God sees us in – would it really be
us God sees in each observation? It would seem that by imagining me as a Chinaman or African (or perhaps as an inhabitant of some sort of alien world)
I would cease to be me, and become an entirely new person. Hence it wouldn’t really be me God sees making these alternative choices, it would be a different person (or creature I suppose) in each observation.
Then I began to ponder the creative process and how we are given a soul by God. Believe me I’ve heard perhaps every theory under the sun, including very viable theories that assert all souls were created at once (at creation). However, what we at least know for sure is that God endows us with a soul and He know the who, what, and where (since we know God is omniscient, omnipresent, and omnipotent – even if you’re OVT you at least believe the latter two are true, which is enough for the following example).
In other words when a person is conceived or born into a cannibalistic tribal village in a jungle somewhere with no contact with the outside world God knows He is placing a soul into a person who will be born into such circumstances. This is the one consistent fact with every creation theory I’ve encountered.
Considering this we have to seriously ask ourselves, does God really give every person on the planet a genuine opportunity at faith in Christ? The answer is obviously and resoundingly no.
Calvinism fits nicely with the scriptural text, while other theories I’ve studied simply require too much in the way of theological gymnastics to force into the text of scripture. They also require us to ignore logical a little bit too much for my taste.
Don’t get me wrong I do think there is a level of randomness in the universe. I do also believe God can see the future. However, with regard to election God actually chose us before the founding of the world for reasons that have nothing to do with us. We might view this as arbitrary but that is only if we view it from our perspective, and not God’s.
