Verse 29 adds to the reference to clothing a repeated prohibition as to the other half of our anxieties, and thus rounds off the whole with the same double warning as in verse 22. But it gives a striking metaphor in the new command against 'being of doubtful mind.' The word so rendered means to be lifted on high, and thence to be tossed from height to depth, as a ship in a storm. So it paints the wretchedness of anxiety as ever shuttlecocked about between hopes and fears, sometimes up on the crest of a vain dream of good, sometimes down in the trough of an imaginary evil. We are sure to be thus the sport of our own fancies, unless we have our minds fixed on God in quiet trust, and therefore stable and restful. Verse 30 gives yet another reason against not only anxiety, but against that eager desire after outward things which is the parent of anxiety. If we 'seek after' them, we shall not be able to avoid being anxious and of doubtful mind. Such seeking, says Christ, is pure heathenism. The nations of the world who know not God make these their chief good, and securing them the aim of their lives. If we do the like, we drop to their level. What is the difference between a heathen and a Christian, if the Christian has the same objects and treasures as the heathen? That is a question which a good many so-called Christians at present would find it hard to answer. But the crowning reason of all is kept for the last. Much of what precedes might be spoken by a man who had but the coldest belief in Providence. But the great and blessed faith in our Father, God, scatters all anxious care. How should we be anxious if we know that we have a Father in heaven, and that He knows our needs? He recognises our claims on Him. He made the needs, and will send the supply. That is a wide truth, stretching far beyond the mere earthly wants of food and raiment. My wants, so far as God has made me to feel them, are prophecies of God's gifts. He has made them as doors by which He will come in and bless me. How, then, can anxious care fret the heart which feels the Father's presence, and knows that its emptiness is the occasion for the gift of a divine fullness? Trust is the only reasonable temper for a child of such a father. Anxious care is a denial of His love or knowledge or power.
