THE SPIRIT.

28. To these two John adds a third witness, "the Spirit." The Spirit bears witness with the water and the blood; in fact, through these other two he operates. It is the Holy Spirit himself; not as he is invisible up in heaven in his divine essence, but the Spirit who publicly manifests himself through his external office and permits himself to be heard through his Word. As John here asserts, the Spirit bears witness on earth with both the water and the blood.

29. Neither Moses nor any other teacher in his doctrines of personal effort and external purifications, his washings and his sprinklings of the blood of sheep and goats—no such teacher brings and gives the Spirit. With them is no Spirit, no divine power, no regeneration of man. Any unbelieving, spiritless, wicked knave can exercise human effort and practice physical cleansing. But Christ alone brings with him the power and presence of the Holy Spirit, who sanctifies us through the blood and water issuing from the divine side. The Spirit makes us partakers of its cleansing influence through the external office of preaching and through the sacraments, which are called the office and gifts of the Holy Spirit. Through these the Spirit works in the Christian Church just as he did at first, among the apostles on the Day of Pentecost, and will continue to do in the whole world, unto the last day. Without his ministration we would never obtain, nor know anything about, the saving power of Christ's blood in baptism.

30. Such is the kingdom Christ unceasingly develops through the Christian Church. In him we have eternal purification when to the water is added the Spirit, who through the Word enkindles the heart and purifies it, not with the cleansing qualities of the water alone, but with the healing efficacy of the blood of Christ, whereby sins are exterminated and God's wrath appeased. Although the work of our redemption was wrought once for all in Christ's blood shed upon the cross and is sufficient to cancel the sins of the entire world, yet Christ so instituted it that the same efficacy should remain forever, and be daily distributed and offered to us through the Holy Spirit.

31. This work of the Holy Spirit is neither received nor perceived except through faith in this witness, the preached word of Christ—when with the heart man grasps it and confidently believes it is fulfilled in himself as the Word declares. Thus is the heart really cleansed, the individual born anew, through the Holy Spirit present in the sacred cleansing of water and of the blood of Christ.

Peter (1 Pet 1, 2) speaks of the sanctification of Christians as the "sprinkling of the blood of Jesus Christ" upon us by the Holy Spirit through the public preaching of the Gospel. This sprinkling radically differs from the Jewish sprinkling of water, or of the ashes of a red heifer, or of the blood of a dead lamb or goat, round about the altar and upon the applicants for purification. In the sanctification of Christians, the true consecrated water and the sprinkled blood of Christ are combined; that is, the message concerning the shed blood of our Lord Jesus Christ is "sprinkled," so to speak, upon the soul, and wherever that Word touches the soul it is effective. The blood in this case is not the ineffective, lifeless blood of a slain animal, but the potent, living blood of the Son of God. Under its application the soul cannot remain impure. Christ's blood purifies and heals from sin and death; it strikes at their very foundation, and entirely releases us from their power and grants us eternal life for soul and body.

32. Note, this text is a grand sermon on the witness Christians have here on earth, which the apostle in concluding explains and extols in beautiful and comforting words. He calls it a witness that God himself bears to his Son and that serves to assure us of being the children of God and possessors of eternal life. For he says: "And the witness is this, that God gave unto us eternal life," etc. This is indeed an excellent witness, which God himself witnesses and declares to you, and the Holy Spirit brings and reveals to you. God cannot lie nor deceive, he is the eternal, unchangeable truth, as already mentioned. If you believe this witness, you certainly have received and possess it, as John again says: "He that believeth on the Son of God hath the witness in him."
