It is possible he is wrong, though given he and his advisors theological background and personal dedication I am far more apt to believe their stand on this issue, than those evangelicals that dismiss without merit a theory that as I have said before at its best simply offers a "HOW" God may have worked... God is the answer to "WHY" not "how".
Human experience can observe the world and theorize and even prove the HOW something works or behaves... however when it comes to the answer of "WHY"... that is the realm of God.
Evolution does not remotely suggest WHY or even attempt to deal with WHY... it is merely an theory on "how".
I agree with you passionately that God is the answer to Why and that Darwinian evolution isn't. I just don't agree that DE is the answer to how. I think the better answer is to admit we don't know how.
