"But seek ye first the kingdom of God and His righteousness, and all these things will be added unto you."- Matthew 6: 33
So peeling off from yesterday's discussion in terms of purpose and doing, perhaps I'll start with those things that Christ Himself said. Today's verse comes from the Sermon on the Mount, where Christ is discussing the various attitudes that will be true of Christians, and that obeying God is a matter of the heart as much as it is a matter of outward actions. The verse above comes at the end of the discussion concerning serving a master - either God or mammon (money). The comparison is made between unbelievers, who seek after money ("What shall we eat? What shall we drink? What shall we wear?") and the followers of Christ, who are apparently to do something else.
What? Certainly not go naked and hungry through a lack of attention! -Christ says that their Father in heaven knows that they have need of "all these things". But in counter to the question of seeking these things, of serving money (by extension, I suppose, the world and all our own "empire building"), we are seek the Kingdom of God and God's righteous."
In seeking, we are looking for something diligently to find it. In this case, the Kingdom of God - which, God says elsewhere, is not found in eating and drinking but in righteousness and peace and joy in the Holy Spirit (Romans 14:17). We are additionally to seek the righteousness of God - as found in God's son Jesus Christ, the offering for our sin, and therefore our salvation.
Do I seek Christ as my salvation daily - to the extent that I am not concerned about more mundane things (concerned to the point of worry)? How does what I perceive I should be doing in my life, about my goals, relate to seeking the kingdom of God (righteousness, peace, joy) and Christ? Are they building up His kingdom, or mine?
