Behold, he comes with clouds; and every eye shall see him, and they also which pierced him…
I cannot put into English the full meaning of that most expressive word. Sound it at length, and it conveys its own meaning. It is as when men wring their hands and burst out into a loud cry; or as when eastern women, in their anguish, rend their garments, and lift up their voices with the most mournful notes. All the kindreds of the earth shall wail: wail as a mother laments over her dead child; wail as a man might wail who found himself hopelessly imprisoned and doomed to die. Such will be the hopeless grief of all the kindreds of the earth at the sight of Christ in the clouds: if they remain impenitent, they shall not be able to be silent; they shall not be able to repress or conceal their anguish, but they shall wail, or openly give vent to their horror. What a sound that will be which wilt go up before high heaven when Jesus sits upon the cloud, and in the fulness of His power summons them to judgment! Then "they shall wail because of Him." Will your voice be heard in that wailing? Will your heart be breaking in that general dismay? How will you escape? If you are one of the kindreds of the earth, and remain impenitent, you will wail with the rest of them.
(C. H. Spurgeon.)
