Jesus did not come to separate us from the natural world.  Jesus was the reason for Creation in the first place.  It was Love [the Love of God for the Son] that sparked the creation of the world.  "For God so loved the world..."

It is those who still live in the ancient Gnostic-split of natural vs. supernatural---who see the natural as only a painted back-drop to the work and action of God---which they believe is only concerned about the supernatural.  God created humans as material-spiritual units.  We are not complete without concern for both aspects of our humanity.  Jesus spent much of his public caring for the needs of the hungry, the sick, the poor.  As disciples of Jesus, we are also called to make all of creation TRULY GOOD, by modeling ourselves after Christ and walking in his Light.
