Argument from Mathematics
Primary question: Does the existence of necessary, abstract mathematical truths, and their uncanny applicability to the physical world, point to a divine mind as their ground?

Common mistakes
Don't say
Assuming mathematical Platonism alone already implies theism.
Instead
Recognize that non-theistic Platonism is a serious, widely held position and that the argument requires showing theism explains the data better.
Don't say
Treating the unreasonable effectiveness claim as beyond dispute.
Instead
Acknowledge selection-bias responses and cite specific historical cases that are harder to explain that way.
Don't say
Overstating that this is a mainstream argument among philosophers of mathematics.
Instead
Note that theistic conceptualism is a minority position competing with nominalism, structuralism, and naturalistic Platonism.
What would change my mind? — Christian position
A fully successful nominalist reconstruction of all of applied mathematics without any commitment to abstract objects, or a compelling naturalistic solution to the access problem, would substantially weaken this argument.
What would change my mind? — Skeptical position
Evidence that theistic conceptualism faces the same or worse explanatory difficulties as its rivals, such as an inability to explain why God's necessary thoughts would take precisely the mathematical form they do, would reduce its comparative advantage.
Why does this matter?
The argument from mathematics matters because it draws on one of the most stable and impressive achievements of human reason, mathematics itself, to probe deep metaphysical questions about necessity, abstract truth, and the structure of physical reality. It connects philosophy of religion with philosophy of mathematics, a field with its own rich, largely independent debates, giving the argument unusual intellectual texture. Because mathematical Platonism itself is contested and the theistic solution is a minority position even among theists in this field, the argument functions best as one strand within a cumulative case rather than a stand-alone proof.
