Along York Lane in the Sydney CBD are alcoves and recessed doorways set into the buildings.

It was in one of these recessed doorways where a man named Karl used to live (or rather, sleep).

Hundreds of people passed Karl every day - and sadly, in 2013, Karl died in his sleep, exposed on York Lane.

However, in a remarkable postscript, his long-lost brother, who had been searching for Karl for decades, finally found him.

And he brought him home.

"My son," the father said, "you are always with me, and everything I have is yours. But we had to celebrate and be glad, because this brother of yours was dead and is alive again; he was lost and is found." - Gospel of Luke, Chapter 15
