Why is Jesus looking on an oddly standing stone? I am not a Christian, so please excuse my Philistinism if I'm missing the obvious, but ever since I saw this painting on my Grandma's wall I've been intrigued by it. Particularly the standing stone in the foreground and by the odd little stare Jesus seems to give it.
Question: Does anyone know if there's any deeper (Biblical) meaning to it?

&quot;Christ in the Desert&quot;, Ivan Kramskoy, 1872
From the title of the picture, I feel it is safe to assume the author had this in mind:

Matthew 4:1-4


  1 Then was Jesus led up of the Spirit into the wilderness to be
  tempted of the devil.
  
  2 And when he had fasted forty days and forty nights, he was
  afterward an hungred.
  
  3 And when the tempter came to him, he said, If thou be the Son of
  God, command that these stones be made bread.
  
  4 But he answered and said, It is written, Man shall not live by
  bread alone, but by every word that proceedeth out of the mouth of
  God.


The stone is so oddly standing in order to stick out. Otherwise it wouldn't be Jesus staring at a stone, it would be Jesus staring.
