thinking through next week's sermon on "Belief."
Here's my thought:
God has revealed exactly enough of Himself/evidence for His existence so as to ensure that you can believe but withheld exactly enough of Himself/evidence so as to ensure that you are not compelled to believe, thus offering you salvation while protecting your free agency.
(And the issue is "Why doesn't God just show Himself to us in proof-positive ways?" not Calvinism vs Arminianism, so... )
