The Holy Spirit is called “the Spirit of grace” in Heb. x. 29, “Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden underfoot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto _the Spirit of grace_?” This name brings out the fact that it is the Holy Spirit’s work to administer and apply the grace of God: He Himself is gracious, it is true, but the name means far more than that, it means that He makes ours experimentally the manifold grace of God. It is only by the work of the Spirit of grace in our hearts that we are enabled to appropriate to ourselves that infinite fullness of grace that God has, from the beginning, bestowed upon us in Jesus Christ. It is ours from the beginning, as far as belonging to us is concerned, but it is only ours experimentally as we claim it by the power of the Spirit of grace. XXII. _The Spirit of Grace and of Supplication._ The Holy Spirit is called “the Spirit of grace and of supplication” in Zech. xii. 10, R. V., “And I will pour upon the house of David, and upon the inhabitants of Jerusalem, _the Spirit of grace and of supplication_; and they shall look unto Me whom they have pierced: and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for his first-born.” The phrase, “the Spirit of grace and of supplication” in this passage is beyond a doubt a name of the Holy Spirit. The name “the Spirit of grace” we have already had under the preceding head, but here there is a further thought of that operation of grace that leads us to pray intensely. The Holy Spirit is so called because it is He that teaches to pray because all true prayer is in the Spirit (Jude 20). We of ourselves know not how to pray as we ought, but it is the work of the Holy Spirit of intercession to make intercession for us with groanings which cannot be uttered and to lead us out in prayer according to the will of God (Rom. viii. 26, 27). The secret of all true and effective praying is knowing the Holy Spirit as “the Spirit of grace and of supplication.” XXIII. _The Spirit of Glory._
