When I talked with Karen yesterday she asked that we pray for a couple of things specifically:
-that her, Steve and brother Caeden would be able to get some rest
-that through Joel's life and death that others would come to know Christ personally.
I would ask that you would also pray that they would feel God's presence and comfort each day as they will miss little Joel so very much.
