In the sacred constitution of the person of our Lord Jesus Christ, as God and Man united in one personal agent. Here majesty and mercy give a glorious instance of their union, here all the grandeur and dignity of the Godhead condescends to join itself in union with a creature, such as man is, a spirit dwelling in flesh and blood. 1 Timothy 2:5: There is one God, and one Mediator between God and man, even the Man Christ Jesus: but this Man is personally united to the blessed God, He is God manifested in the flesh. He is a man in whom dwells all the fullness of the Godhead bodily, to constitute one all-sufficient Savior of miserable and fallen mankind. What an amazing stoop or condescension is this for the eternal Godhead thus to join itself to a creature! And what a surprising exaltation is this of the creature, for the Man Christ Jesus thus to be assumed into so near a relation to the blessed God! All the glories that result from this divine contrivance and transaction are not to be enumerated in paper, nor by the best capacity of writers here on earth; the heavenly inhabitants are much better acquainted with them.

   Again, here is an example of the harmony and co-operation of unsearchable wisdom and all-commanding power in the person of the blessed Jesus; and what a happy design is hereby executed, namely, the reconciliation of sinful man and the holy and glorious God. Who could do this but one who was possessed of such wisdom and such power? When there was no creature in Heaven or earth sufficient for this work, God was pleased to appoint such a union between a creature and Creator, between God and man, as might answer all the inconceivable purposes concealed in His thought. If there be wanting a person fit to execute any of His infinite designs. He will not be frustrated for want of an agent: He will appoint God and man to be so nearly united as to become one agent to execute this design.
