Where is the rule that says we cannot be BOTH rational and directed? Do our children not make rational decisions while under our full control? Of course they do. The experience is the same with us. And does the Bible say anywhere that we would be less than human without the Apostolic view of free will?
The Gospel assumes free will. Without free will, it becomes meaningless.
I'm sorry, FK, but it's just flat ridiculous to say we do not have free will. You're exercising yours right at this moment.
The only way to make Calvinistic theology cogent is to define free will as something other than what everyone experiences as free will: making decisions in their lives, hopefully better ones growing in wisdom.
