The Holy Spirit A B Simpson Chapter 10 – The Holy Spirit in the Epistle to the Romans Inside of all this is the principle of life, and inside of this is the Holy Ghost in the consecrated believer. He is most distinctly represented to us here as a vital force in our material being, a source of life, quickening, exhilaration and physical energy for those that know Him and obey Him. He is the Spirit that raised up Christ from the dead, and He dwells in our mortal bodies as a quickening life. This is not the immortal body of the resurrection, but the mortal frame of the present life which feeds upon the divine life. And this is the secret of living on the life of God.
