Bit, rudder, fire. Bit, rudder fire.
I repeated it over and over to myself for days. In the book of James it says;
"A bit in the mouth of the horse controls the whole horse. A small rudder on a huge ship in the hands of a skilled captain sets a course in the face of the strongest winds. A word out of your mouth may seem like no account, but it can accomplish nearly anything- or destroy it!
It only takes a spark, remember, to set off a forest fire. A careless or wrongly placed word out of your mouth can do that..." (James 3:3-6 MSG)
Out of (seemingly) no where I had remembered hearing a very smart woman speak on controlling your tongue. The context was completely different. She wasn't talking about parenting, but God used her words none the less.
