The First Adam moved in selfishness and misused his authority in the Garden.  Jesus, the Last Adam, moved in love and used his authority to ransom humanity by the shedding of His own blood.  Love is the only key (and motivation) that enables the Remnant to move in true Kingdom authority and function in the Kingdom as Jesus did.  In fact, there is a biblical connection of love with keeping the commandments of God and reaching spiritual maturity.
