James,

You started this off to be thoughtful and worthwhile. Why then do you have to conclude by setting up a strawman between natural processes and God? What is that attempting to suggest? That we are all Liars for Darwin again?

Why did God have to be intimately involved with the creation of man through Adam and Eve? Would you still worship Him if He wasn't? What if the scientific evidence ends up falsifying this position? You may look like a buffoon like the YECs do.

And are you sure it is God you are choosing? I don't think so. Judging from this sanctimonious and pompous, gratuitous and self incriminating inane remark, I think you may be choosing an idol of imaginary concordism that gives you the upper hand and intellectual superiority you are looking for so you have a perceived advantage in fighting the culture war.

The bottom line is that neither your concordism or pure naturalism will likely ever be proven. But your concordism can be falsified while God working through natural processes cannot be. So why insist on it? And why is it not choosing God to not insist on it?

John
