The reference itself comes from Haggai 2:6-7: For thus saith the LORD of hosts; Yet once, it is a little while, and I will shake the heavens, and the earth, and the sea, and the dry land; And I will shake all nations, and the desire of all nations shall come: and I will fill this house with glory, saith the LORD of hosts.
It reminds me of this passage from Isaiah 9. This obviously deals with Adventing, but it also holds truth I would do well to remember when I want to get all freaked out and angry at the state of the world.
For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the increase of his government and of peace there will be no end, on the throne of David and over his kingdom, to establish it and to uphold it with justice and with righteousness from this time forth and forevermore. The zeal of the LORD of hosts will do this.
Of the increase of His government and peace there will be no end...The zeal of Yahweh, Lord of the hosts of the armies of heaven, will accomplish this!
God's Kingdom is always increasing, always growing, always taking ground, all around the world - even when it seems that the darkness is only getting darker. Yet God is always revealing Himself! All the peoples, all the nations will know His light!
And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb. By its light will the nations walk. Revelation 21:23-24
For now, we cling to what John says, "The Light shines in the darkness, and the darkness has not overcome it."
