Here is the resolution of the whole chapter. Seeking first the kingdom means living under God’s direction and control. The verb is a present imperative, which means a constant state of preoccupation, a daily reorientation of the heart back to God. This is why the daily disciplines matter. Our lives drift. If we are not returning to God each day in prayer and the Word, we slowly start believing the lie that we have got this, that we do not really need Him.
The kingdom disciple asks a different question about every decision. Not can I afford it, not what do I want, but what does God’s way require here? That is a different set of ambitions. And to it Jesus attaches a promise: all these things will be added to you. This is not a promise of affluence. It is a promise of provision, not what we want but what we need. The Father who knows your needs and whose way you seek will Himself supply them.
Jay Adams said the worrying person needs not reassurance but reorientation. Reassurance says everything will be fine, and it soothes for fifteen minutes before the worry returns. Reorientation asks what value system is producing the anxiety, what is functionally on the throne, and then calls us to put the kingdom there instead. Pursue the kingdom and the things follow. Pursue the things and you will end with neither the things nor the kingdom.
