This book was very short - 186 pages. McGrath assumes a lot, and his argument wanders a lot. This leaves me short on understanding his position.
It seems he feels that we (Western culture) have come to see nature as an "adversary" (to be conquered), rather than a "gift" (to be stewarded).
I can't help but think this is the result of his evolutionary thinking.
We see a glimpse of this on page 180:
"The issue of pain and suffering in the world remains something of a puzzle, and at times troubles Christians considerably."The evolutionist must believe that God created suffering, because it is good - it pleases Him. This is definitely a puzzlement!
It reminds me most of "Ishmael", who takes this thinking to its logical conclusion - that we must allow human death as "most natural". Allow famine, allow the weak to die - to resist is unnatural ("sinful").
McGrath doesn't seem to go this far. But it is like his logic is leading him there, and he knows it is wrong. But he can't figure out why, so he says nothing (or says it is "a puzzle").
