Seek first his kingdom and his righteousness, and all these things will be given to you as well (Matthew 6:33). 


What is the Kingdom of God?


Wherever God rules is his Kingdom. The Kingdom is both present (Luke 11:20; 17:20-21) and future (Matthew 26:29; Revelation 11:15). … If Jesus rules in your heart, then the Kingdom of God is in your heart and you are part of the Kingdom. The Kingdom already exists on Earth within believers. It can't be seen, but it is there. And there is coming a day when the Kingdom will be over all the Earth. 


What does it mean to seek the Kingdom?


To seek means to look for, to chase after, to pursue. It's an action. Often we seek things we are passionate about. The next cool tool we need for the shed, that new game that looks like hours of fun, videos of horses, tutorials on how to build, cook, train, or play, the new Star Wars Pop! figure. We seek these things because we're passionate about them. We even sacrifice other stuff like our time and money. We should be passionate enough about Jesus that we seek, chase, and pursue the Kingdom, sacrificing our time and money to advance it. Do you have a passion like that?


Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find him, and with him everything else (C. S. Lewis in Mere Christianity).
