"You probably own a power vacuum. Have you ever tried to vacuum your rug without plugging it in? I doubt it. You know that you need a power source to get the job done. You'd never consider vacuuming any other way. So, why do so many of us live under our own power rather than being plugged in to the supernatural power of God? His power is always available, but we must choose to access it."
This is why running out of our own steam is actually a good thing...we can finally let God be God in our lives.
