The tagline to the new McDonald’s ad campaign is “Think With Your Mouth.”

I suppose it’s another way of saying “Forget about calories; if it tastes good, eat it.” Probably not the best nutritional advice you’ll hear today.

However, when it comes to what you say, the slogan works.

Most of us have a tendency to speak first and think second. It leads us to say things we don’t really believe: “This situation is out of control … Nothing good can come of this … Nothing ever works out … There’s no point in trying.” And so on.

We’re like the people of Israel who offended God with their words in Malachi 3. We criticize and complain. We talk defeat and despair. We say things that couldn’t possibly be true — not if the God we serve is truly all-powerful.

Learn to think with your mouth. Practice speaking out words of faith. “God is in control. He has a solution and it’s on its way. This will work out for the best, because he causes all things to work out for the best. He will guide me through me my fear and uncertainty, and lead me each step of the way.” And so on.

Before you blurt what you don’t believe, stop. Think with your mouth. Speak God’s Word first.

This book of instruction must not depart from your mouth; you are to recite it day and night so that you may carefully observe everything written in it. For then you will prosper and succeed in whatever you do. (Joshua 1:8 HCSB)
