1. Worry Wastes Time and is Unnecessary
Worry is ineffectual. We don’t accomplish anything or find answers to our questions by worrying. We also cannot add anything to our life by worrying.

Worry cannot correct errors or make the future better. Hence, there is no need for worry because it is inessential.

2. Worry Invites the Problem
By focusing on what we do not want we actually increase the likelihood of them coming to pass.
There is also considerable evidence that worry has negative impact on our health.

3. Worry Distracts us From Solutions
Worry distracts us from addressing things that can resolve existing challenges. By dwelling on our fears we lessen our capacity to take decisive action to correct problems. Also, worry dampens our happiness.

Jesus is as usual quite clear on the issue of worry:
Do Not Worry
Luke 12: 22 Then Jesus said to his disciples: “Therefore I tell you, do not worry about your life, what you will eat; or about your body, what you will wear. 23 Life is more than food, and the body more than clothes. 24 Consider the ravens: They do not sow or reap, they have no storeroom or barn; yet God feeds them. And how much more valuable you are than birds! 25 Who of you by worrying can add a single cubit to his height (single hour to his life[b])? 26 Since you cannot do this very little thing, why do you worry about the rest
