Verse 10 (Ecclesiastes 9:10) is no more a divine revelation concerning the state of the dead than any other conclusion of "the Preacher" (Ecclesiastes 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. (Ecclesiastes 9:4). A living dog is better than either. No one would quote verse 2 (Ecclesiastes 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; (Genesis 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. (Isaiah 14:9-11); (Matthew 22:32); (Mark 9:43-48); (Luke 16:19-31); (John 11:26); (2 Corinthians 5:6-8); (Philippians 1:21-23); (Revelation 6:9-11).
