Free Will
Primary question: Do human beings have libertarian free will, and if so, how is this compatible with God's exhaustive foreknowledge, sovereignty, and grace?

Common mistakes
Don't say
Treating 'free will' as a single, agreed concept in these debates.
Instead
Specify whether libertarian or compatibilist freedom is meant, since much apparent disagreement is really a disagreement about definitions.
Don't say
Assuming one tradition (usually one's own) has simply solved the problem others have failed to solve.
Instead
Recognize that Calvinist, Arminian, Molinist, and Thomist accounts are each internally coherent responses to the same data, carrying different costs.
Don't say
Citing sovereignty texts or responsibility texts in isolation as though the other set did not exist.
Instead
Read both sets of texts together and ask which model best honors the weight of each, rather than proof-texting one side.
What would change my mind? — Christian position
Discovering that Scripture's exhortation and judgment language is merely rhetorical with no underlying real agency would remove the coherence of the moral and covenantal structure of the biblical narrative.
What would change my mind? — Skeptical position
A rigorous philosophical demonstration that theological determinism and genuine moral responsibility are strictly logically incompatible (rather than merely intuitively uncomfortable) would force compatibilist Christians to abandon their position, though it would not by itself refute Arminian or Molinist alternatives.
Why does this matter?
How one resolves the freedom-sovereignty question shapes preaching, prayer, evangelism, and pastoral counsel: whether one urges 'choose today' language with an Arminian sense of genuine contingency, prays for God to sovereignly regenerate a hardened heart in Reformed confidence, or holds both together with Molinist or mysterian humility, the practical shape of Christian life is affected even when the underlying metaphysics remains contested among careful, orthodox thinkers.
