Do Not Disturb

Again, while watching Joyce Meyer this morning, God dinged me on head. 

Do I put a "Do Not Disturb" on me when I go to church, to the store etc?  Yes I do.  Well, actually, mine is more like, BACK OFF BUSTER!!     Seriously and more importantly, I wear it when mom is in the room.  I'm guessing God wants me to take it off, tear it up, burn it and start wearing a "Welcome" sign instead.  How can I be used by God when I am wearing the wrong sign?
