The science fiction move "Predestination" is a fascinating and mind-blowing study in time travel paradox. It is the most thought-provoking sci-fy movie I've seen. (After watching the movie, you will find an in-depth explanation of the all the paradoxes here. Do NOT read it before watching the movie.)
Most intriguing to me is how powerfully the movie depicts predestination with free choice - just as Scripture affirms. The main character cannot change what is predestined, but all the choices are truly his free choices. Scripture affirms both, whether we can explain how it works or not. The Gospel of John presents salvation as neither solely God’s election, nor is it solely man’s free choice of the will. Salvation is equally both. It is a dichotomy and yet a paradox from our perspective. God’s sovereignty and man’s free will are both present in salvation even though they stand in constant tension with each other. Ultimately how God's sovereignty uses the free choice of man is a mystery that resolves itself only in the Divine Mind. While it is beyond human comprehension, both are simultaneously true. The movie does a masterful job of secularly presenting both as true.
Even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, (Eph 4:1-5, ESV)
And if it is evil in your eyes to serve the Lord, choose this day whom you will serve, whether the gods your fathers served in the region beyond the River, or the gods of the Amorites in whose land you dwell. But as for me and my house, we will serve the Lord.” (Joshua 24:15, ESV)
The heart of man plans his way, but the Lord establishes his steps. (Prov 16:9, ESV)
