Matthew 6:33

seek first God’s kingdom and His righteousness, and all these things (food, drink, clothes, etc.) will be given to you as well. 

What does Jesus mean to seek God’s righteousness?

From a human perspective, righteousness in relation to God is right standing with Him. Some people believe that God judges us based on the totality of good versus bad deeds. To practice a “good life” in order to gain God’s favor would be an example of seeking righteousness with God.

But that is not what Jesus is telling us to seek. Rather, He is calling us to seek after God’s way of making people right. That comes through faith in God and in His only-begotten Son Jesus as Lord. To seek after that righteousness is to pursue God through Jesus – His ways, His teachings, His Lordship, His call to deny ourselves, to pick our cross, and to follow Him.

Seek this first.

Luke 6:46-49

The Wise and Foolish Builders
46 “Why do you call me, ‘Lord, Lord,’ and do not do what I say? 47 As for everyone who comes to me and hears my words and puts them into practice, I will show you what they are like. 48 They are like a man building a house, who dug down deep and laid the foundation on rock. When a flood came, the torrent struck that house but could not shake it, because it was well built. 49 But the one who hears my words and does not put them into practice is like a man who built a house on the ground without a foundation. The moment the torrent struck that house, it collapsed and its destruction was complete.”
