My soccer coach used to tell me all the time.  If you practice sloppy, you will play sloppy in the game.  If you practice lazy, you will play lazy in the game.  If you practice crisply, you will play crisply in the game.  I found it to be very true.  

I also find it to be true in our Christian walk.  Join us as we look at the importance of living daily to prepare ourselves for the formidable opponent.
