The Day of The Lord is Coming..Joel 1-2.

The word of the Lord that came to Joel the son of Pethuel. Hear this, you elders, And give ear, all you inhabitants of the land! Has anything like this happened in your days, Or even in the days of your fathers? Tell your children about it, Let your children tell their children, And their children another generation. Alas for the day! For the day of the Lord  is at hand; It shall come as destruction from the Almighty. Blow the trumpet in Zion, And sound an alarm in My holy mountain! Let all the inhabitants of the land tremble; For the day of the Lord is coming, For it is at hand: The earth quakes before them, The heavens tremble; The sun and moon grow dark, And the stars diminish their brightness. “Now, therefore,” says the Lord, “Turn to Me with all your heart, With fasting, with weeping, and with mourning.” Blow the trumpet in Zion, Consecrate a fast, Call a sacred assembly; Fear not, O land; Be glad and rejoice, For the Lord has done marvelous things! Then you shall know that I am in the midst of Israel: I am the Lord your God And there is no other. My people shall never be put to shame.
