The Christian god cannot be understood by the human ratio. He's by definition bigger than that. (Read the Hiob story in the bible- a story that was always among the most difficult to understand for me).

Independent of that question: We have forgotten many aspects of nature as we have cars, heatings, planes, dams- we think we can dominate nature (and we do it in many ways- just look at the extinction of animals due to a lack of living space all over the world.)

But at the end of the day the destruction power in nature itself is bigger than even ours: there are rivers (we had a big flood in Germany two years ago), volcanoes (do you remember Mt St. Helens), earthquakes, tsunamis.......... and we better shouldn't forget that.

Whether it makes sense that the world is like this is something I cannot answer.
