Luke 12:25-26: "And which of you by worrying can add a single hour to his life's span? If then you cannot do even a very little thing, why do you worry about other matters?" (NASU).
Do you worry? Most of us do, and yet Jesus tells us very clearly we have nothing to worry about. In fact, He tells us it is counterproductive! We don't need to worry because we know how the story ends. If our hope is assured (Heb 11:1), we shouldn't be concerned about the sorrows of today or tomorrow. "Worry does not empty tomorrow of its sorrow," said Corrie Ten Boom; "it empties today of its strength."
How do we inoculate ourselves against worry? The answer is faith. When our hearts are fixed on God's Kingdom, we see life from an eternal viewpoint. We are able to put God's goals first. The question we must keep asking is, "Where is our heart?" If our hearts are fixed on worldly things, we will always worry because the world's treasures are uncertain. If our hearts are fixed on God, we will rest in His power and strength.
Great faith can cancel out worry.
