Anxiety is the price we pay to continue our illusions of control.  The things that worry us are very often the things we have no control over. Jesus says not to worry about a number of things: what we eat and drink, our bodies, and our clothing. And he goes on to say that worrying is futile because worrying does not add any time to your life (in fact, it takes away joy because you could be doing other things when you worry).

As soon as we finally accept that we are no longer in control of our lives, then anxiety begins to lose its grip over us. And that means trusting our father and his plan for our lives. We don’t know all that God has in store for us, but we know that He is faithful, and that he will not forsake those who trust in Jesus. Worry implies that God doesn’t know our care about our needs. Therefore, don’t worry (says Jesus). For our heavenly father knows what we need, which isn’t necessarily what we want.
