"For thus saith the high and lofty One that inhabiteth eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones." Isaiah 57:15
O what a mystery that God should have two dwelling-places! The "heaven of heavens" that "cannot contain him;" and the humble, broken, and contrite heart! But in order that the Lord of heaven might have a place in which he could live and lodge, God gives to his people gifts and graces; for he cannot come and dwell in the carnal mind, in our rebellious nature, in a heart full of enmity and wickedness; he therefore makes a lodging-place for himself, a pavilion in which the King of glory dwells, the curtains of which are like the curtains of Solomon. His abode is that holy, divine nature which is communicated at regeneration--"the new man, which after God is created in righteousness and true holiness." Thus Christ dwells in the heart by faith; and is "in his people, the hope of glory." And this made Paul say, "I am crucified with Christ; nevertheless I live; yet not I, but Christ lives in me; and the life which I now live in the flesh, I live by the faith of the Son of God, who loved me, and gave himself for me."
This is the object of God's dealings--that the Lord God might dwell in his people; that there might be a union between the Church and her covenant Head--"I in them, and they in me, that they might be perfect in one." This is the unfolding of the grand enigma, the solution of the incomprehensible mystery, "God manifest in the flesh,"--that the Lord God might dwell in his people; "I will dwell in them, and walk in them; and I will be their God, and they shall be my people;" and thus glorify himself by filling their hearts with his grace and glory, as Solomon's temple was of old, and that they might enjoy him, and be with him when time shall be no more. This is the grand key to all the Lord's dealings with the soul, and all his mysterious leadings in providence--that the Lord God might dwell in the hearts of his people here, and be eternally glorified in them in a brighter and a better world.
