I like the New Living Translation of Philippians 4:6, "Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done."
Like the words of Jesus in Matthew 6 where he tells us not to worry about tomorrow, and to receive God's daily provision for today, these words are familiar to all who have been a Christian for some time.
But they get right to the heart of our faith: if we continue to worry then we have a limited view of God, of who He is, and of His love and power to provide for us. The consequence of living this way is that the best that can be said is that we have a faith, rather than living by faith. Living by faith is not easy, it's a journey, even a battle. It's certainly a constant set of choices to live in a certain sort of way. Merely having a faith as a lifestyle accessory is much less demanding, but it's not how Christians are meant to live.
