The meaning of this passage hinges on the first "therefore." You cannot serve God and selfish gain at the same time, says Jesus; you should choose decisively to serve God; and _therefore_ you must not be anxious about yourself. For _anxious fear so concentrates a man's thought on himself that he can serve no one else_. That this is the meaning of this familiar passage is clear also from its conclusion. The real reason for conquering anxious fear is that a man may give himself wholeheartedly to the service of the Kingdom. That fear does spoil usefulness is obvious; a man cannot be fearful for himself and considerate of his fellows. As Stevenson puts it in "Aes Triplex," "The man who has least fear for his own carcass has most time to consider others. That eminent chemist who took his walks abroad in tin shoes and subsisted wholly upon tepid milk had all his work cut out for him in considerate dealings with his own digestion. So soon as prudence has begun to grow up in the brain, like a dismal fungus, it finds its first expression in a paralysis of generous acts." The shame of our fearful living is that it circles about self, is narrowed down to mean solicitudes about our own comfort, and is utterly incapable of serving God or seeking first his Kingdom. Only faith puts folk at leisure from their small anxieties so that they can be servants of a worthy cause. Jesus, therefore, in this passage is not giving us the impossible injunction not to think about tomorrow; he is stating a truth of experience, that anxious fear for oneself which so draws in the thought that God's great causes are forgotten is a deadly peril in man's life. By faith thrust out the mean and timid solicitudes, is his injunction, that life may be free to put first things first.
