“The Holy Spirit is the great gift of the [New] Covenant. His coming from heaven was the proof that the Mediator of the Covenant was on the throne in glory, and could now make us partakers of the heavenly life.
"He is the only teacher of what the Covenant means: dwelling in our heart, He wakens there the thought and the desire for what God has prepared for us.
"He is the Spirit of faith, who enables us to believe the otherwise incomprehensible blessing and power in which the New Covenant works, and to claim it as our own.
"He is the Spirit of grace and of power, by whom the obedience of the Covenant and the fellowship with God can be maintained without interruption.
"He Himself is the Possessor and the Bearer and the Communicator of all the Covenant promises, the Revealer and the Glorifier of Jesus, its Mediator and Surety.
"To believe fully in the Holy Spirit, as the present and abiding and all-comprehending gift of the New Covenant, has been to many a one an entrance into its fullness of blessing.”
Andrew Murray, The Two Covenants
