I'm sorry I can't remember very much of it, but it includes the line 'You shone out of the darkness, into our hearts' or something like that (reference to 2 Corinthians!) The music was fairly contemporary. I believe it was #490 in the hymnal. We sang it at Mass this morning right before communion, but I forgot to jot down the name of it and have been googling furiously ever since! :D
Does anyone know the one I'm talking about?
