My son's 6th grade leadership teacher uses that phrase with her students. I found this out when I stuck my spoon (uninvited) into the bowl of ice cream Kid Two was scooping out for himself.
He shot me a look and recited with confidence (or was it sarcasm?), "Um, we don't do that here." I apologized (but I wasn't entirely sorry. Come on, it was chocolate chip ice cream!) It was a simple statement that let me know his position without question. His mind had already been made up. His 'matter of fact' response confirmed he wasn't putting up with any shenanigans. Apparently 'we' don't take ice cream from another family member without asking. who knew.
This morning when I was wrestling in prayer about a thing or two, the enemy started in on me. Familiar lies that I so easily believe, making me feel less than God says I am, and trying to convince me I'm never going to live up to what God has called me to do -- I was letting him take my ice cream without asking.
I interrupted his condemnation. "Um, excuse me, we don't do that here." I told him with confidence. I stopped the voice that was trying to weaken me because the facts say I belong to the Father. And the voice that condemns me belongs to the enemy.
I refused to listen any longer. He has no audience here.
We won't sheepishly believe we won't measure up.
We won't walk in guilt because we fall short from time to time.
We won't give up the pursuit because it's work.
Sorry, we don't do that here.
