It’ ain’t no use putting up your umbrella till it rains. – Alice Caldwell Rice
Worry has become an obsession in our modern world. A look at the self-help section in any bookstore will reveal its prevalence. Hospitals and waiting rooms are filled with people who have physical problems caused by overwhelming anxiety. In addition, there are many people whose lives are disrupted or made unenjoyable because of paralyzing fear.
Simon Patrick said, “It is distrust of God to be troubled about what is to come; impatience against God to be troubled with what is present; and anger at God to be troubled for what is past.”
What seems clear is that we often worry about things over which we have no control, or about events and circumstances that never occur. For this, we lose the joy of today and add a burden to an already difficult day.
Life’s too short for worrying. “Yes, that’s what worries me,” we reply.
I saw this saying recently on a church sign along the road: worry does not take the trouble, it takes the peace of the day.
Rather we should know that one is given strength to bear what happens to one, but not the one hundred and one different things that might happen. 
John Dryden commented that “Only man clogs his happiness with care, destroying what is, with thoughts of what may be.”
Only one type of worry is correct: to worry because you worry too much.
Christians like to hide their worry by labeling it Christian concern. In spite of protestations to the contrary, Christians do worry. But, do they have to? Not if they learn from Jesus how to win over worry.
Paul spoke in similar terms in 1 Timothy 6:6-10: “But godliness with contentment is great gain. For we brought nothing into the world, and we can take nothing out of it. But if we have food and clothing, we will be content with that. People who want to get rich fall into temptation and a trap and into many foolish and harmful desires that plunge men into ruin and destruction. For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs.”
The believer can be content no matter what the outward circumstances: Philippians 4:11-13: “I am not saying this because I am in need, for I have learned to be content whatever the circumstances. I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. I can do everything through him who gives me strength.”
When we look at life against the message of the life of Jesus and His teachings, the risen life is not easy: it is also a dying life.  We should make it our priority and purpose.
Contentment finds an opposite in the form of worry. The words of Jesus early in His public ministry suggest that food and lodging should be enough for the godly: Matthew 6:34: “Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.”
There is plenty to worry about (vs. 25). There is no shortage of potential items to worry about. Jesus mentions several matters of common concern: life, health, possessions, We could add our own list of concerns: accidents, aging, weather, or criticism.
There is nothing accomplished by worry (vv. 26-33). It is senseless. The rest of God’s creation does not worry, but God provides for them. Will he not do the same for us. This does not say we should not work, only that we should not worry while we work (v. 26, 28). It is fruitless. It will not add an inch to your height or a hour to your life. In fact, it may well take away from your life (v. 27). It is harmful. Worrying makes us look like the heathen, and it destroys our witness. 
Worry, he says, is characteristic of a heathen, and not of one who knows what God is like (verse 32). Worry is essentially distrust of God. Such a distrust may be understandable in a heathen who believes in a jealous, capricious, unpredictable god; but it is beyond comprehension in one who has learned to call God by the name of Father. The Christian should not worry because he believes in the love of God.
Worry gives a small thing a big shadow. Worry is an indication that we think God cannot look after us. Worry is like a rocking chair. It gives you something to do but doesn’t get you anywhere.
