THE SOURCE OF FAITH.

18. Thus we have the first part of our sermon on the new birth and faith. For the second part, John shows whence and by what means comes the faith productive of victory; he says: "This is he that came by water and blood, even Jesus Christ; not with the water only, but with the water and with the blood. And it is the Spirit that beareth witness, because the Spirit is the truth. For there are three who bear witness [in earth], the Spirit, and the water, and the blood," etc.

19. John speaks of Christ's kingdom, and of the office the Holy Spirit bears outwardly and visibly in the Christian Church, represented in the ministerial office and the sacraments. He says: "There are three who bear witness [in earth]." John, as usual, employs the word "witness" in connection with the thought of preaching; it is a word he frequently uses. For instance, in the beginning of his gospel, where he speaks of John the Baptist, he says (ch. 1, 7): "The same came for a witness, that he might bear witness of the light." So, in his use of the phrase "witness" or "bearing witness," we are to understand simply the public preaching of God's Word. Again, Christ says (John 16, 9-14), that the Holy Spirit shall bear witness of him; that is, he shall publicly fill the ministerial office. This is God's own witness to his Son. And here John tells us we have the victory over the devil and the world, through faith, for the sake of Christ the Son of God.

20. This witness Christ himself ordains shall ever go forth, and remain, in the Church. To this end Christ sent the Holy Spirit; to this end Christ himself called and gave the Holy Spirit to the apostles and their successors, ministers, preachers and teachers, as Paul tells us (Eph 4, 11-13), who are to exercise the Word, that the Word may resound always and everywhere in the world, reaching to children's children, and on down to future generations. Were the witness not in the Church, the pulpit—in fact, the entire outward administration of the Church—would be useless, for every man could read the Scriptures for himself. But for the sake of the uninstructed masses and the constantly rising young who, as yet in ignorance of the Word, need admonition—for the sake of these, the Spirit must bear public witness or administer the preaching office that they, too, may learn to know the grace of God manifest and given to us through Christ, and that God's wondrous works may be publicly recognized and extolled by us in opposition to the devil and the world.

21. Wherever such witness is borne, there certainly will be some fruit. The witness never fails of effect. Some surely will be reached; some will accept and believe it. Since it is the witness of the Holy Spirit, and the apostle says here, the Spirit beareth witness, he will be effective, producing in us that to which John refers when he says we are children of God, and have the victory and eternal life. So the Word—or the Gospel message accompanied by the witness of the Spirit—and faith are vitally related. In the last analysis they are inseparable. Without faith, preaching will be fruitless; and faith has origin in the Word alone. Therefore, we should gladly hear and handle the Word. Where it is, there is also the Holy Spirit; and where the Spirit is, there must be at least some believers. Even if you have already heard the Word and obtained faith, it will always continue to strengthen you as you hear it. One knows not at what hour God may touch and illumine his or another's heart. It may be in a time when we least look for it, or in the individual of whom we have least expectation. For the Spirit, as Christ says, breathes where he will, and touches hearts when and where he knows them to be receptive.

22. It is relative to the power and energy wrought by the Holy Spirit that John speaks, indicating the source and means of the power of this witness, when he says of Christ, "This is he that came by water and blood," etc. In this sentence is included all we possess in the kingdom of Christ, and here is extolled the efficacy of our beloved baptism and the blood or sufferings of Christ. Here John unites all the elements in one bundle, so to speak, making a triune witness. They bear joint witness to our faith and confirm it—these three: the water, the blood and the Spirit.
