I've never heard anybody address the Kingdom in this way...
Taken directly from my daily-email-dose-of-Stott:
The Kingdom of Heaven (cont'd.)
60. Total blessing and total demand
When Jesus spoke of the kingdom of God he was not referring to the general sovereignty of God over nature and history, but to that specific rule over his own people which he himself had inaugurated, and which begins in anybody's life when he humbles himself, repents, believes, submits and is born again. God's kingdom is Jesus Christ ruling over his people in total blessing and total demand. To 'seek first' this kingdom is to desire as of first importance the spread of the reign of Jesus Christ. Such a desire will start with ourselves, until every single department of our life -- home, marriage and family, personal morality, professional life and business ethics, bank balance, tax returns, lifestyle, citizenship -- is joyfully and freely submissive to Christ. It will continue in our immediate environment, with the acceptance of evangelistic responsibility towards our relatives, colleagues, neighbours and friends. And it will also reach out in global concern for the missionary witness of the church.
