"Which of you by worrying can add one cubit to his stature?" Matthew 6:27
Worrying doesn't change things. A cubit is 18 inches, or approximately 45cm. We cannot, by worrying about a situation, grow in height by a cubit – or, for that matter, by a fraction of that measure – it just won't work.
Today is the tomorrow you worried about yesterday. Now it hasn't turned out so bad, has it? So why worry?
The antidote for worry is trust - trust Jesus – you'll do a lot better. Give Him your cares and worries, and He will make a way.
