We have many good conversations about predestination. But we seldom define the degree to which predestination affects the universe and all.
At the least it appears many think God imagined the universe before he created it. Let it run its own course without his intervention. And then created what he saw. Making it unchangeable and therefore predestined to happen just as he foresaw it.
Another view, the most extreme says: God created all, including every thought and act of every creature in the universe when he created the universe. That not a grain of sand on the furthest planet shifts position without God who also created its path and movements in the appointed time.
Both extremes depend on God’s perfect knowledge. If God only energizes but doesn’t control all, he then must watch and learn what might or might not happen. And this would mean he is not all knowing as the bible says.
Other theories emerge but the Westminster Confession Chapter 3:1; God's Eternal Decree defines biblical predestination this way.
- God, from all eternity, did—by the most wise and holy counsel of his own will—freely and unchangeably ordain whatever comes to pass. Yet he ordered all things in such a way that he is not the author of sin, nor does he force his creatures to act against their wills; neither is the liberty or contingency of second causes taken away, but rather established.
So as I understand, we freely choose for the reasons God created with us, to base our choices on. As we meet up with them at the right time in life.
This resolves free will and divine sovereignty.
