My advice would be not to worry about what is going to happen to you: about what you will have to eat or drink, or about what clothes you will wear. your life doesn’t consist of eating, and there is much more to your body than clothing. Take a lesson from the birds of heaven. They don’t sow or reap or hoard away to granaries, and your Father – the One in the heavens around you – sees to it that they have food. Aren’t you more important than birds?
Who can change their physical features by worrying about them? And as for worrying about clothes, well, look at the little flowers out in the fields. They just pop right up. They don’t slave away getting or making clothes. But King Solomon in his best outfit was not as glorious as one of these. Now if God so adorns the wild grasses – which are here for a day, and the next day are burned for fuel – won’t he do even better by you? You mini-faiths!
So don’t worry about things, saying, “What are we going to eat?” or “Will we have anything to drink?” or “What will we wear?” (People who don’t know God at all do that!) For your Father – the One in the heavens around you – knows you need these things. Instead, make it your top priority to be part of what God is doing and to have the kind of goodness he has. Everything else you need will be provided.
Tomorrow? Don’t worry about it. You can do your worrying about tomorrow tomorrow. And anyway, enough will happen today to keep you in things to worry over until bedtime.
– Dallas Willard, quoting Matthew 6 in The Divine Conspiracy
