Verse 10 (Ecc 9:10) is no more a divine revelation concerning the state of the dead than any other conclusion of "the Preacher" (Ecc 1:1) is such a revelation. Reasoning from the standpoint of man "under the sun" the natural man can see no difference between a dead man and a dead lion. (Ecc 9:4). A living dog is better than either. No one would quote verse 2 (Ecc 9:2) as a divine revelation. These reasonings of man apart from divine revelation are set down by inspiration just as the words of Satan; (Gen 3:4); (Job 2:4); (Job 2:5) are so set down. But that life and consciousness continue between death and resurrection is directly affirmed in Scripture. (Isa 14:9-11); (Mat 22:32); (Mar 9:43-48); (Luk 16:19-31); (Joh 11:26); (Co2 5:6-8); (Phi 1:21-23); (Rev 6:9-11).
