“How do you reconcile an omnipotent (all powerful, no constraints upon Him other than those that are self-imposed) God who is omniscient (knows every possible outcome of every action before the action is even contemplated, by Him or by humanity) who would set up the circumstances as they are/were, with a God who is also purportedly omnibenevolent (desiring nothing but good for His creations)?”
This is actually not tough to reconcile when you think about it. Indeed, God knows all, has all power, and wills only good.
However, has he not given us free will? And is not free will the ability for us, as human persons, to actually do things on our own accord - that is, the ability to will distinctly (if not necessarily separately) from God’s will? If God has truly given us truly free will, then he implicitly humbles Himself to the extent that we can do things according to our own will. So even though he CAN do anything, He shares with us His creative power and humbles Himself to the point that we can actually affect our reality of our own accord.
Though we can affect our reality and our state, God still know what we will choose to do. That does not, however, mean that he actually chose what we would do Himself. The gift of free will is often underrated, so to speak - we, in a certain sense, have determined what God knows by our choices. Not because of any power originating withing ourselves, but because we reflect God’s creative nature when we exercise our free will.
So then, God offers man the choice to be with Him or to stray. Although God knows that man may, in fact, stray away, what else is He to do if He has actually offered us free will? By a contingent being’s very nature, it cannot experience the infinite divinity of God until it has chosen Him - but until it has chosen to love Him, it is still susceptible to temptation.
Since God willed Adam to love Him, He offered Adam the choice to follow or stray. Even though He knew Adam would stray before He created Him, He knew this BECAUSE of Adam’s choice. God did not will evil, but, in humility, allowed Adam to retain his free will.
This seems to limit God’s omnipotence, but it does not; rather, it reflects His humility. It is on the cross that God most explicitly expresses His humility; yet, it is in this humility that we see the most profound expression of His omnipotence. His ability to make us anew in holiness, we who have immersed ourselves in sin.
