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.
