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. 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 his life? Since you cannot do this very little thing, why do you worry about the rest? (Luke 12:22-26)
