The following excerpt was taken from an article by Roland over at his blog Two Natures. I found it insightful.
Evolution and the Incarnation
In a stereotypical creationist-vs.-atheist debate, I have no one to root for. Both sides have already lost me before the debate even begins. Once the debate is joined, it looks like they disagree on every single point, and that is how they are usually perceived. To me, however, it seems that they agree with each other on the central premise that underlies the debate: in the provocative form attributed to Richard Dawkins, "If Darwin's cosmology was right, then theology is senseless babble." And creationists like Phillip Johnson accept the premise and join the debate on those terms. This all-or-nothing proposition, for those who accept it, validates both the conflict and the energy they expend on it.
When combatants on both sides find a rare proposition they can agree on, one is tempted to let it pass without further examination. But this premise is both illogical and heretical. It assumes that God's only purpose is to serve as a causal explanation of phenomena in the physical universe, and that if a completely natural explanation can be found for every phenomenon then we can dispense with God as redundant and dismiss the supernatural entirely. This argument might be compatible with a Deistic "God of the gaps," but it cannot be reconciled with the God of orthodox Christianity. We believe that Jesus was both fully divine and fully human – that these two natures dwelt in him without contradiction. From this orthodox Christian understanding of the Incarnation, it follows that the supernatural is not excluded by the natural; rather, the supernatural manifests itself in and through the natural. Therefore, even if science were somehow to demonstrate the truth of an entirely materialistic explanation of the universe, it could not exclude the existence or activity of God.
Therefore, from an orthodox Christian point of view, a debate premised on the mutual exclusivity of the natural and the supernatural is flawed from the outset.
