I'm the world's worst for keeping my car on empty. My theory is that I get better gas milage by keeping my fuel load light. $10 bucks at a time, every day or so, that's my game plan. 

But apparently the shelf life on a 4-runner's fuel sensor is about 213,000 miles. So I recently started playing the old odometer game. Fill up, reset the odometer, and keep the odometer below 400. Now I'm not quite so confident in my splash-and-go stategy. I check the odometer more often than I check my mirrors, and if it hits triple digits I start second guessing if I remembered to reset it.

We can do the same thing with our spiritual tank. If we're not careful, we start relying on the fuel light to tell us when we're getting low. But God didn't create us to run on fumes. His desire is to fill us with the Spirit so we can fully enjoy the fellowship with Him!
