“Positionally, our sanctification by the Spirit results from our being vitally united to Christ, for the moment we are livingly joined to Him, His holiness becomes ours, and our standing before God is the same as His. Relatively, our sanctification of the Spirit issues from our being renewed by Him, for the moment He quickens us we are set apart from those who are dead in sins. Personally, we are consecrated unto God by the Spirit’s indwelling us, making our bodies His temples. Experimentally, our sanctification of the Spirit consists in the impartation to us of a principle (“Nature”) of holiness, hereby we become conformed to the Divine law. Let us consider each of these viewpoints separately.
Our union to Christ is the grand hinge on which everything turns. Divorced from Him, we have nothing spiritually. Describing our unregenerate condition, the apostle says, “at that time ye were without Christ,” and being without Him, it necessarily follows “being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world” (Eph. 2:12). But the moment the Holy Spirit makes us livingly one with Christ, all that He has becomes ours, we are then “joint-heirs with Him.” Just as a woman obtains the right to share all that a man has once she is wedded to him, so a poor sinner becomes holy before God the moment he is vitally united to the Holy One. Everything which God requires from us, everything which is needed by us, is treasured up for us in Christ.” – A. W. Pink
