29 And do not set your heart on what you will eat or drink; do not worry about it. 30 For the pagan world runs after all such things, and your Father knows that you need them.
31 But seek His kingdom, and these things will be given to you as well.
Here's a stark contrast between what God wants us to do and what we naturally want to do left to our own devices. We worry and fear and compete. God wants us to trust Him, depend on Him, and do as He does/has shown us to do. We want to gather, accumulate and defend what we've hoarded. "Mine, Mine, Mine!" And we do it all following Machiavelli's philosophy "The ends justifies the means." Following the world's rules; "all's fair in love and war" and "finder's keepers, losers weepers," "possession is 9/10ths of the law," and "he who dies with the most toys wins."
