But what, exactly, is failure? Failure, by one definition, is "the condition or fact of being insufficient or falling short"1. Romans 3:23 immediately comes to mind: "For all have sinned and fall short of the glory of God."
All of us fail; we all fall short! Somehow, it's so hard to remember that we do not have any righteousness of our own; rather, it is a gift and it comes only by faith. The same passage of scripture in Romans 3 fits so well:
What we need to do is to trust God to help us through all our days. The next time we feel as if we have fallen short, we need to realize that true righteousness comes from God alone, and He alone can strengthen us and make us righteous.
