I tell you, do not worry about your life, what you will eat; or about your body, what you will wear. For life is more than food, and the body more than clothes. 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!  Who of you by worrying can add a single hour to your life? Since you cannot do this very little thing, why do you worry about the rest?

Luke 12:22-26
