“Eternal perspective” as used in evangelical preaching, usually amounts to docetism. Only what is done for Christ will last, and so on. The implication — intended or not, people imbibe it — is that only the ghostly souls of men will pass into the next age; spend as little work as possible on things like art, engineering, plumbing, which are Works of Hay and Straw, to be burned up on the last day.
