It is only the manufacturer that knows when something is not operating or built to the proper operating efficiency. The Bible is our operation manual. How we are to run is spelled out within the pages verse by verse.
So operating efficiently is really all about trust. Are you willing to take your life (vehicle) off the road for necessary repairs so God can use you for His Kingdom. It takes trust to do this. Trust to pull into time with Him regardless of what else is happening on the road of life. We must make the necessary repairs or it is only a matter of time before we find ourselves along the road of life dealing with a breakdown.
The Bible says, whoever tries to keep his life will lose it. Luke 17:33 (NIV) "Whoever tries to keep their life will lose it, and whoever loses their life will preserve it."
Your success does not lie in your own human effort. Kingdom success relies on your trust in God.
