By the rivers of Babylon we sat and wept when we remembered Zion. There on the poplars we hung our harps, for there our captors asked us for songs, our tormentors demanded songs of joy; they said, “Sing us one of the songs of Zion!”
How can we sing the songs of the LORD while in a foreign land? If I forget you, Jerusalem, may my right hand forget its skill. May my tongue cling to the roof of my mouth if I do not remember you, if I do not consider Jerusalem my highest joy.
Remember, LORD, what the Edomites did on the day Jerusalem fell. “Tear it down,” they cried, “tear it down to its foundations!” Daughter Babylon, doomed to destruction, happy is the one who repays you according to what you have done to us. Happy is the one who seizes your infants and dashes them against the rocks. j
Well that ending makes me sick. But it's not necessarily an emotion endorsed by God, it's just one honestly expressed by a writer who had seen evil things (probably those very things) done to his own people. And then he had the courage to say it to God. I pray that we will have the courage to tell God what we are really feeling and thinking, in the confidence that he can handle it and that it will help us to move on to a better relationship with him.
