Careers, life partners, finances, location, and education should never be our chief focus. All of these things will be sorted out and added to us as we keep the Kingdom of God as our primary concern. As we seek God's will for our lives, we can be sure that it will never move us in a direction that is contrary to God's Kingdom purposes.
The imperative of seeking God's Kingdom is not only relevant in the context of highly spiritual ministry issues. Jesus says that if we seek the kingdom first, all these things will be added to us. This is one of the most powerful secrets to discovering God's will for your life. If you will set your sights on His Kingdom and make that your priority, as you move toward it you will automatically come across everything else you need!
Once after I had finished preaching about the Kingdom of God, an elder in the church approached me and said, "You know, all these lofty ideas are wonderful, but most of the people in the church are just trying to figure out how to pay their bills and get along with their spouse and raise their kids and do a good job at work". I realised that in many ways this dear friend was right. Most Christians consider the Kingdom of God to be something so lofty that it is best left to pastors and evangelists.
