Sir, I perceive that thou art a Prophet. The fruit of the reproof now becomes evident; for not only does the woman modestly acknowledge her fault, but, being ready and prepared to listen to the doctrine of Christ, which she had formerly disdained, she now desires and requests it of her own accord. Repentance, therefore, is the commencement of true docility, as I have already said, and opens the gate for entering into the school of Christ. Again, the woman teaches us by her example, that when we meet with any teacher, we ought to avail ourselves of this opportunity, that we may not be ungrateful to God, who never sends Prophets to us without, as it were, stretching out the hand to invite us to himself. But we must remember what Paul teaches, that they who have grace given to them to teach well [1] are sent to us by God; for how shall they preach unless they are sent? (Romans 10:15.)

A prophet - One sent from God, and who understood her life. The word here does not denote one who foretells future events, but one who knew her heart and life, and who must therefore have come from God. She did not yet suppose him to be the Messiah, John 4:25. Believing him now to be a man sent from God, she proposed to him a question respecting the proper place of worship. This point had been long a matter of dispute between the Samaritans and the Jews. She submitted it to him because she thought he could settle the question, and perhaps because she wished to divert the conversation from the unpleasant topic respecting her husbands. The conversation about her manner of life was a very unpleasant topic to her - as it is always unpleasant to sinners to talk about their lives and the necessity of religion - and she was glad to turn the conversation to something else. Nothing is more common than for sinners to change the conversation when it begins to bear too hard upon their consciences; and no way of doing it is more common than to direct it to sonic speculative inquiry having some sort of connection with religion, as if to show that they are willing to talk about religion, and do not wish to appear to be opposed to it. Sinners do not love direct religious conversation, but many are too well-bred to refuse altogether to talk about it; yet they choose to converse about some speculative matter, or something pertaining to the mere "externals" of religion, rather than the salvation of their own souls. So sinners often now change the conversation to some inquiry about a preacher, or about some doctrine, or about building or repairing a place of worship, or about a Sunday school, in order to seeM to talk about religion, and yet to evade close and faithful appeals to their own consciences.

I perceive that thou art a prophet - And therefore thought him well qualified to decide the grand question in dispute between the Jews and the Samaritans: but she did not perceive him to be the Messiah.

The woman saith unto him, Sir,.... With another countenance, and a different air and gesture, with another accent and tone of speech, dropping her scoffs and jeers:
I perceive that thou art a prophet; such an one as Samuel was, who could tell Saul what was in his heart, and that his father's asses were found, and where they were, 1-Samuel 9:19; and as Elisha, whose heart went with his servant Gehazi, when Naaman turned to him to meet him, and give him presents; and who could tell, ere the king's messenger came to him, that the son of a murderer had sent to take away his head, 2-Kings 5:26. And such a prophet, that had such a spirit of discerning, this woman took Christ to be; and who indeed is greater than a prophet, and is the omniscient God; who knows all men's hearts, thoughts, words and actions, and needs not that any should testify of them to him; for he knows what is in them, and done by them; and can tell them all that ever they did, as he did this woman, John 4:29. Now in order either to shift off the discourse from this subject, which touched her to the quick; or else being truly sensible of her sin, and willing to reform, and for the future to worship God in the place and manner he had directed, she addressed Christ in the following words.

Sir, I perceive, &c.--Seeing herself all revealed, does she now break down and ask what hopes there might be for one so guilty? Nay, her convictions have not reached that point yet. She ingeniously shifts the subject from a personal to a public question. It is not, "Alas, what a wicked life am I leading!" but "Lo, what a wonderful prophet I got into conversation with! He will be able to settle that interminable dispute between us and the Jews. Sir, you must know all about such matters--our fathers hold to this mountain here," pointing to Gerizim in Samaria, "as the divinely consecrated place of worship, but ye Jews say that Jerusalem is the proper place--which of us is right?" How slowly does the human heart submit to thorough humiliation! (Compare the prodigal; see on Luke 15:15). Doubtless our Lord saw through the fetch; but does He say, "That question is not the point just now, but have you been living in the way described, yea or nay? Till this is disposed of I cannot be drawn into theological controversies." The Prince of preachers takes another method: He humors the poor woman, letting her take her own way, allowing her to lead while He follows--but thus only the more effectually gaining His object. He answers her question, pours light into her mind on the spirituality of all true worship, as of its glorious Object, and so brings her insensibly to the point at which He could disclose to her wondering mind whom she was all the while speaking to.

Sir, I perceive that thou art a prophet. Every word that Jesus had uttered had excited her wonder more and more, and when he lifted the curtain off her life, she was convinced at once of his superhuman knowledge.

Sir, I perceive - So soon was her heart touched.
