John 4:42

and said unto the woman, Now we believe, not because of thy saying; for we have heard Him ourselves, and know that this is indeed the Christ, the Savior of the world.

The woman did her missionary work well. She spoke with such earnestness and conviction that she persuaded many of the people of the city. Their faith was the result of the woman's testimony, even before they saw and heard Jesus Himself. If we only, individually and collectively, see to it that the Gospel is proclaimed throughout the world, we may rest assured in advance that the blessing of God will attend our efforts, and that there will always be some that will come to faith and acknowledge Jesus as their Redeemer. And the testimony of the woman caused also the petition of the Samaritans that the Lord should stay with them. For two days they were privileged to have the Savior in their midst. He taught these souls that were hungry for salvation; He gave them the information which they needed concerning His person and work. And the harvest was rich and plentiful. A great many more were gained through the preaching of Jesus, who frankly told the woman that they no longer believed on account of her narrative. They themselves had heard the words of eternal grace, they had the firm knowledge and conviction that this man was not a mere teacher or prophet, but that He was truly the Christ, the Savior of the world. That is the simple, but unshakable certainty of Christian faith. That is the right faith, that we do not only believe to be true what we hear in regard to the wonderful spiritual experiences of others, but that we have the personal conviction regarding Jesus that He is our Savior.
