Sometimes perceived losses can actually be blessings in disguise. For instance, perhaps you were late for work in frustrating fashion, or something appeared to not be going your way, but that event ended up saving you from a car crash that you will never know you were spared from. Only God can see all ends. As frustrating as one might feel about the pitfalls and setbacks, it is important to remember the truth that God works all things together for the good of those who love Him. Trust is the key to peace when the Goliaths oppose you. No matter what it is that comes up against you, you can harden your resolve and determine yourself to believe that God is with you and nothing can stop you from victory. Perhaps that frustrating situation is exactly the pathway you needed and you could not perceive it. But God knows.
