His kingdom is actualized and come upon us whenever we follow His will. Just like Jesus Christ obeyed His will to be crucifed on the Cross despite of His status as Son of God and ability to summon angels. It is a perfect example that to prompt us to seek Lord's perfect will, hence follow it in our respective fields and blessed timetable. We ought to pursue His righteousness and His acknowledgement daily. Think about it again, how many times have we embittered by our own sense of righteousness?
