Psalm 137:5
I like thinking of this psalm because it has so much longing for Jerusalem, a place at the heart of this Holy Land I've grown to love so much. I like to remember, though, that the psalm is about a real exile from the city experienced by real people.
For one thing, I've met people, Arab Christians, who feel that same longing for Jerusalem and almost that same feeling of exile, rarely even able to visit the city only 6 miles away.
For another thing, the psalm isn't just about ancient Israel or even geographical Jerusalem. Jerusalem represents the real home of humanity, the heavenly city. We're all in exile here on earth. So let's go back home.
