The woman then left her water pot, and went her way into the city, and said to the men,

She left, &c. "Having heard Him say," saith S. Augustine, ""I am He that talketh with thee," and having received the Lord Christ into her heart, what could she do but leave her pitcher, and run to preach the Gospel?" For she knew that Jesus must be a Prophet because He had revealed to her the secrets of her heart. When therefore He declared that He was Messias, she believed in Him, knowing that He was a man worthy of credit, who could neither deceive, nor be deceived. Wherefore she ran into the city without delay, fearing lest Jesus might go away if she tarried. As S. Chrysostom says, "She had come to draw water, but as soon as she found the true Fountain she despised the other; and by the grace which came down upon her from above, she discharges the office of an Apostle."
For this is the Spirit of Christ, to infuse into those whom He converts zeal for converting others, that they may make others partakers of that great benefit which they feel in themselves. Elegantly and piously does S. Ambrose write of this (Serm30): "By a new kind of marvel, the woman, who came to the well of Samaria a harlot, went away chaste from the fountain of Christ. And she who came to fetch water carried back modesty. For as soon as the Lord showed her her sins, she knew and confessed them: she announced Christ to be the Saviour. And leaving her water-pot at the well, she does not carry a pitcher back to the city, but she brings grace. She seems to return without a load, but she goes back full of sanctity. She returned full, I say, because she came a sinner, she returns a preacher. And she who had left her water-pot carried back the fulness of Christ. She brought back no harm to her city, for though, it is true, she carried no water to it, she brought them the whole well of salvation."
