Instead of worrying about yourself, care for others ...

 "Don't worry about your life," says Jesus.

           "Don't be afraid."

           Instead of hoarding money, give it away. Instead of worrying about yourself, care for others. Beyond all your prudent planning for the cares of life, abandon yourself to a fatherly God who is all-powerful and intimately personal. After you've hedged every bet and calculated every contingency, enjoy the beauty of the morning birdsong and the glory of a field of flowers. Having fretted over a life of worries, whether artificial or genuine, consider an act of faith. Live like what you believe is actually true. After you've run yourself ragged like a godless "pagan" (12:30), says Jesus, rest in the knowledge of a benevolent Being.

dealing with wealth creatively

We should probably begin this passage with the preceding verse, which speaks of seeking the kingdom and receiving what one had been anxious about. Certainly the opening verse sets the framework for what follows. God wants to give us the kingdom! That needs unpacking. It means God wants us to benefit from what will happen when God’s will finally triumphs. To long for the kingdom is to long for something which is promised and promising. Our ultimate hope then rests in God’s own being as one who wants to give. This is trust which sets us free.
It sets us free to deal with wealth creatively. 12:33 speaks of selling property and using the proceeds for others. Today this is complex, but the principle is simple. The complexity of our situation can be our camouflage for inaction. The reality is that we need to address the underlying possessive anxieties which our world has a way of escalating. When we do so, then we can be free to let our wealth go and use it (as wisely as our best caring strategies determine). This is both something which grace generates and something where the sequence is not automatic. Grace needs a shove because the sophisticated rationalisations for selfishness create heavy drag.
