The work of the Holy Spirit in the life of Christ, including equipping Him for that work, has received considerable attention from Reformed, perhaps particularly from Puritan, theologians. It is a Biblically grounded and theologically significant topic that we would do well to remember and understand. Hugh Martin sets it out briefly:
Whatever therefore is now requisite or suitable in Him that shall be acknowledged as the last Adam, Head of the redeemed of God, First-born among many brethren, standing in the room and at the head of all, that the Holy Spirit shall now work gloriously by His grace in the Man that is Jehovah’s fellow, and redeemer of the sons of men. Far-reaching wisdom, and understanding, and insight into the Father’s eternal counsel with Himself the eternal Son (Isa. 11:2), shall now dwell in His human intellect. Sympathy profound with the Father’s electing love shall now beat true and tender in His human heart. Compassion for the countless perishing ones, and adoring desire for His Father’s glory in their salvation, shall now qualify Him to preach the gospel to the poor, to heal the broken hearted (Isa. 61:1; Luke 4:18). Patience unmurmuring; perseverance, in the face of hell’s floods of opposition; mercy, in the face of men’s malice and rejection of Him; longings for His cross, and agonies till His baptism of blood be accomplished (Luke 12:50); all these graces, and all others needed in His office, now publicly assumed and entered on, will the Holy Spirit of His baptism unfailingly, and unto the uttermost, operate in Jesus, the Head and Mediator of His Church.
