What does God wish for eternity for His Creation? I have had (and still have) pets. Does that separate them from the others of their species? Does this thread imply that my two guinea pigs get to go to heaven, when the millions of natural guinea pigs who lived in the Andes for tens of thousands of years simply disappear?
Creation is not about man's need (except man's need for salvation), it is about God.
Heaven would defininitely need a lot of sawdust! :-)
