RE: the OP
Not bad, but food for thought...
You can checkmate Calvinism in one move.
Titus 1:2
God does not lie.
Calvinism says God chose those He'd saved ("the elect"). The rest were either actively rejected or merely "passed over." Either way, let's call these unchosen people "reprobates."
TULIP works in reverse, explaining everything the reprobates can't do and why they can't do it. Chief among these, reprobates cannot believe, therefore they cannot be saved. God (according to Calvin himself) simply never intended to do so.
Here's the checkmate:
The Bible invariably shows God condemning unbelief as a specifically grievous sin, and invariably presents it as a willful choice.
If unbelief is a choice (per the Bible) but if unbelief is the result of God's reprobation (per all versions of Calvinism), then we have an irreconcilable contradiction between Calvinism and God. So whenever God condemns someone SPECIFICALLY FOR UNBELIEF, we know that God MUST be lying if Calvinism is true because no one CHOSE to be an unbeliever -- by reprobating them, He chose it for them.
Conclusion: since Titus 1:2 assures us God does not lie, that likewise assures us that Calvinism is irreparably false from the ground up. It is fatally flawed, self-refuting AND BLASPHEMOUS FOR CALLING GOD A LIAR.
