Endurance is the most efficient tool that a racer can possess. It is a thing of advantage that will keep you going even against all odds. It is rewarding to have endurance as it can get you to the finish line where the true reward for running such a long race awaits those who completes it. Endurance is not an easy thing to possess, but if we have genuine love for God in us, it becomes easier for us as motivates us to practice endurance.
Just like in the military, it is not the amount of muscle you carry that will determine how far or rugged you are. Its your endurance.
