Grateful or Greedy?

"This is the bread which the LORD has given you to eat."
 
Many of us are blessed beyond comprehension in this life...but are we appreciative?  Hmm.  If we're hungry and He sends us food, do we say THANK YOU or just complain that it's not our favorite flavor ... or that it took too long to get to the table ... or whine that we're still famished and want seconds? Just a reminder that He provides for us --- and we need to appreciate it.
