Therefore do not be anxious, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For the Gentiles seek after all these things, and your heavenly Father knows that you need them all. But seek first the kingdom of God and his righteousness, and all these things will be added to you.
Right now most people in the world who think about money are worried and anxious about national and world economies. And America is in an unprecedented financial meltdown and government spending spree. Complete collapse of entire economies is possible and looking more probable each day. Yet Jesus spoke these words to peasants who may have not known where their daily food might come from. Most of them were subsistence farmers... people so poor that at times crowds of them did not even take a lunch with them to an all day teaching session because they had nothing to bring!
These words of Jesus address that kind of need. And He says not to be anxious because God is in control and knows all of the life necessities that we have. Our priorities should be matched by devotion. We should seek God and His righteousness above all else, and He will reward the labors of our life with food, and clothing, and shelter.
I do sincerely hope that the current financial situation in the Western world will end the coveting and greed that have marked our culture. I sincerely doubt that they will. Even seventy years ago, in the worst depression ever, people went to movies to lust after the wealth and luxury portrayed there. So I doubt that we will see much change. Still, there is hope that material dearth might foster spiritual thirst, and a true pursuit of God will find in His kingdom and righteousness all that heart is longing for.
