The Kingdom is a remaining Kingdom not a departing one. 
The original plan was that the church should subdue and rule the earth. There is no plan B.  This message proves that God is not intending to "Rapture" the church from the world as the common belief is.  The promise is the coming of Christ and not the going away of the saints. The appearing of Christ and not the disappearing of the church.
Listen to this sermon to clarify what the role of the church is.
