Excerpt taken from my sermon (third in an eight part series) on Ephesians:
There is no doubt that the mission of the Triune God is one grounded and rooted in love. In fact, the members of the Trinity form a covenant of love. The Father loves the Son, the Son loves the Spirit and the Spirit loves the Father and the Son. There is perfect love in the Godhead. The process of heavinifying the earth calls the elect of God to reflect Trinitarian love. This love is to “be thoroughly fixed in our minds, so as to resemble a well-founded building or deeply-planted tree. The true meaning is, that our roots ought to be so deeply planted, and our foundation so firmly laid in love, that nothing will be able to shake us.” If we are unstable in our affections, then we cannot see the deep, deep love of the Father to redeem the world through His son and unite the world under His beloved Son.
 A expression used by few scholars like James B. Jordan, but very appropriate to describe the triune mission.
