"But seek ye first the kingdom of God and His righteousness" This is the matter of real importance. God's interests in that sphere of subjection to His authority (His kingdom) should hold the greatest attraction for us. "His righteousness" is added to this, for everything in the world is contaminated by man's unrighteousness, and it requires purpose of heart to seek the purity of God's righteousness in such contrary circumstances. This does take time and thought. All of these instructions of the Lord in the sermon on the mount are basic in regard to what God's righteousness really is. They are worthy of diligently applied thought and study.
