from Nathan W. Bingham
What in the world would it mean to pray “Thy kingdom come”? Well, it is first of all, an understanding that God has promised a kingdom, that He is Himself a sovereign king, and that in His incarnation and in His saving work—His death, burial, and resurrection-Jesus has inaugurated a kingdom, a kingdom that is not yet fully consummated.
In this sense, inevitably we have to speak, regardless of what may be the specifics of our biblical eschatology, we would we all have to understand that we are right now living in something of an in-between times. We are living between the ascension of Lord Jesus Christ and the decisive events of His coming.
