This is a revolutionary act. It is praying for the establishment of a Kingdom and a Will in which Christ has the preeminence as All in All. In this Kingdom there is no room for any earthly government, ruler, or king. In this Will there is no room for any human agenda. We know Jesus is Lord, yet we do not see all things submitted to Him (Hebrews 2:8).
So what do we do in the meantime? Overcomers do not just passively wait for Jesus to come back. They pray for His Kingdom to be established and for His Will to be performed. In this way they exercise power over the nations by preparing the way of the Lord. So this prayer is destructive in a natural sense, but constructive in a spiritual sense, for as the nations are decreased, Christ is increased (John 3:30).
