We think of earthly kingdoms in terms of territory—an empire. In the New Testament the kingdom of God is not territory. The term is used to describe the reign of God. God’s kingdom today extends over the hearts of all who will acknowledge him as king and who will submit to his rule. They are the same people who desire God’s will in every area of life. To pray “your kingdom come” is to ask God the Father to expand his rule over the territory of our hearts and lives; to pray “Your will be done” (Matthew 6:10) is to express our willingness to submit to his rule whatever the cost.
