Your questions are legitimate and I’ve been through the same wrestling. Those three questions are precisely why I took a step back to see the bigger picture and then I realized something. The issue isn’t the questions themselves, it’s the paradigm behind them.
You’re framing this within the paradigm of chance and necessity (Monod’s framework) where evolution is affirmed as random and unguided. The moment you switch to the paradigm of teleology with Thomas Aquinas’ framework
the questions don’t just get answered, they get reframed.
Through that lens, God didn’t make a mechanistic world that He occasionally intervenes in. He made a teleological world, a world where purpose is built into the fabric of reality. Paul says we are “created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them” Ephesians 2v10. If God prepared works beforehand for us to walk in, then the entire created order is purposeful not random, not provisional, but intentional from the start.
This reframes all three of your questions:
A teleological world doesn’t need to be static to be complete. A seed is complete in its DNA even while it unfolds into a tree. Creation’s completion is in its purpose.
The question shifts from “Did God use random processes?” to “Is randomness real in a teleological world?” If God built purpose into creation’s fabric, then what we call “random” is our epistemic limitation not ontological randomness.
‘The lot is cast into the lap, but its every decision is from the Lord.’
Proverbs 16v33
Then the question shifts from “Are humans transient?” to “Is human identity fixed by purpose or by biology?” If humans are made for good works prepared beforehand, it follows that human identity is teleological because defined by God’s purpose and not by our biology. Christ didn’t become a biological species, He became the purpose for which humanity was created. He is the telos of man, not merely a member of a species.
This is where presuppositionalism and epistemology matter. The real question isn’t “Can science and faith coexist?” That’s a false framing. The real question is: What are your presuppositions about reality? If your presupposition is naturalism aka chance and necessity, then evolution will undermine Scripture because naturalism defines evolution as purposeless. If your presupposition is theism with a God who made a purposeful world for life then indeed evolution is simply the mechanism by which God deploys His intentionality in a world He designed for flourishing.
The choice isn’t between science and faith. It’s between naturalism and theism. The same data looks completely different depending on which paradigm you bring to it.
Ps : None of this conflicts with the problem of evil and biblical theodicy. If we account for the cosmic fall (Satan’s rebellion) as the source of natural evil rather than confining the Fall to Adam’s spiritual death, the theological tension dissolves. Creation can be purposeful and broken because the brokenness comes from a cosmic rebellion with a timeline that the Bible kept hidden, not from God’s ‘unfinished’ design.
