Philosophical Argument
God either exists or God does not exist.

Either I believe in God, or I do not believe in God.

Either we have free will, or we do not.

Suppose free will exists.

Then it is the result of a cause outside of the material universe.

This predicates a spiritual cause.

If there is a spiritual cause, then I believe in God.

Now suppose free will does not exist.

Therefore I am not responsible for my beliefs.

More to the point, I cannot choose my beliefs.

That is, everything about my beliefs that I think I choose, I do not actually choose.

Therefore I choose to believe in God.

I have no other choice.
