I was listening to a song and wasn't sure whether it was sad or joyous, because it sounded both. It was one of many that I heard during a Jewish festival in Warsaw last summer and it was like many of the others: its tune was on the sad side, but it - almost magically - had a joyous ring to it.
I understood where the latter came from, but I stopped for a moment by the former. Then I realised that the sadness, really, wasn't about missing Jerusalem.
It was about missing Jesus.
