How are We Living?

I just came from Wal-Mart, my least favorite place. But I came away doing some serious thinking.
A 20-something young women was face-down on the floor in the bakery area. She had evidently collapsed, and Mustang Fire and Rescue men were working with her. A deli employee held her 3-4 year old daughter. She was just shopping, and suddenly.... She was alive and they were taking her to an emergency room.
But it made me pray and think. I know I could die at any time. But do I live like I know it. If this is the last day I have to tell people about Jesus, am I doing it? If I die today, will I have made an impression with the way I lived me life?
The Bible tells us to go and tell the good news. Do we live like we have good news?
Kind of a somber post, I know, but I really need to make sure people I come in contact with know that I serve Jesus. How about you?
