One way to avoid the kingdom implications of the prayer that Jesus tells us to pray is to claim that presently it’s a spiritual kingdom that will only have substantive, this-world manifestation sometime in the future, either in an earthly millennium or the inauguration of the New Heavens and the New Earth. This way, it’s safe to pray the prayer Jesus wants us to pray since there’s nothing anyone has to do about the kingdom since it is solely the work of God. We can only pray that it comes, that God’s will be done on earth as it is in heaven. Try that with the bread portion of the Lord’s Prayer and see how long you last.
