As I was viewing Twitter today, I came across this one excellent video. Someone has captured both presidents, Bush and Obama, when they first entered to speak to the Marines and when they left. This you probably already know, but it is remarkable to actually see the stark difference.
Here is the link in case the video does not work.
May you walk with the LORD always, and when you cannot take another step, may He carry you the rest of the way until you can walk along side Him again. Digg!
