“Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.”  
John 8:12

There is a certainty of success, victory, no mistakes for you!
You can live your life knowing that decisions you make in life would always lead to victory; you have good information about how your life turned out and you are just following the right steps in real time to ensure it is so.
Jesus said anyone that follow him shall not walk in darkness; so that is the end of confusion and uncertainty in life! There is someone that you will follow and not be concerned that he might be wrong, that he doesn’t know everything, that he might lead you astray! Once you follow his steps; you are placing your feet on the best path.
No more darkness about how to handle that pain in your body, or how to reconcile with your brother, or how to live in abundance, Jesus already said what ought to be done! Do it and you’d certainly see results.
He also said, all who follow shall have the light of life; would possess the strategy of how to do life. There is a way to live on this earth; Jesus knows that way and when you walk with him, what seems like a problem to others would just speak triumph for you.
