What did Jesus say about anxiety and worry?

This is one of the places where my recorded words are fullest and most direct — and where Matthew and Luke preserve the same teaching in slightly different forms, so let me give you both. In the Gospel of Matthew, speaking during what is called the Sermon on the Mount, I said: “don't be anxious for your life: what you will eat, or what you will drink; nor yet for your body, what you will wear. Isn't life more than food, and the body more than clothing” And I pressed the point with an image from nature: “See the birds of the sky, that they don't sow, neither do they reap, nor gather into barns. Your heavenly Father feeds them. Aren't you of much more value than they” Luke records the same teaching with ravens rather than birds generally, and adds a searching practical question: which of you by being anxious can add a single cubit to your height? If you cannot manage even that smallest thing, why carry the weight of everything else? The logic underneath both accounts is the same. Anxiety mistakes what life actually is — it treats food, drink, and clothing as the substance of existence. They are not. The deeper teaching, from Matthew, is this: “don't be anxious for tomorrow, for tomorrow will be anxious for itself” Live within the day you have been given. This is not carelessness about real needs. It is a reorientation of the heart — away from accumulation and fearful grasping, toward trust in a Father who, as I put it, already knows what you need.
