This passage is part of what has become known as the Sermon on the Mount. Jesus is teaching those close to him about how he wants them to live. This message wasn’t for everyone, but only for those who were willing to risk following him and risk going against the culture at that time.
This message offers all of us who are attempting to become a disciple of Jesus Christ guidance about where our focus should be. By stating that we are to strive first for the kingdom of God, it appears that our daily decisions should be made through the lens of God’s kingdom, and not the lens of the world or on our long-term needs. That is hard to do especially when there are so many worldly voices crying out for our attention. May the Holy Spirit assist you in striving first for the kingdom of God before anything else!
