King Jesus and His Mediatorial Kingdom

King Jesus is reigning! Victory is His! So, why do we pray "Thy Kingdom Come?" And why is sin still sticking around? In sermon 6 of "Prayer in the Scriptures" we hear about God's continued work through His Son in the Kingdom of Grace and the Kingdom of Power: One Kingdom under Christ's reign that is already and not yet. Christian, do you pray for Christ's Kingdom to come? Do you desire to see the Father's will done in Earth as in Heaven? Oh, may that be the cry and desire of our hearts.
