…The Holy Spirit was the highest of all gifts that He [Jesus] could solicit from His Father for the exaltation of His people. The Spirit was to be given as a regenerating agent, and without this the sacrifice of Christ would have been of no avail. The power of evil had been strengthening for centuries, and the submission of men to this satanic captivity was amazing. Sin could be resisted and overcome only through the mighty agency of the Third Person of the Godhead, who would come with no modified energy, but in the fullness of divine power. It is the Spirit that makes effectual what has been wrought out by the world’s Redeemer. It is by the Spirit that the heart is made pure. Through the Spirit the believer becomes a partaker of the divine nature. Christ has given His Spirit as a divine power to overcome all hereditary and cultivated tendencies to evil, and to impress His own character upon His church.
