In Isaiah we read, "Ye are my witnesses, saith the Lord." A witness, according to the dictionary, is that which furnishes evidence or proof. One speculating upon mankind in its imperfection reaches the conclusion that, like all other things cognized by the material senses, the witnessing furnished is not of the reality and truth of God, of good, but of evil.
This is true of all things earthly: of discord, of change and dissolution, as breathed through all of materiality, in its proudest moments or in its most beautiful or stupendous prospects. The Persian tentmaker, Omar Khayyam, graphically portrays this in the words,—
The Worldly Hope men set their Hearts
upon
Turns Ashes—or it prospers; and anon.
Like Snow upon the Desert's dusty Face
Lighting a little Hour or two—is gone.
