Charles Spurgeon Commentary John 4:28-42

"So the woman left her waterpot, and went away into the city, and saith to the people, Come, see a man, who told me all things that [ever] I did: can this be the Christ? They went out of the city, and were coming to him. In the mean while the disciples prayed him, saying, Rabbi, eat. But he said unto them, I have meat to eat that ye know not. The disciples therefore said one to another, Hath any man brought him [aught] to eat? Jesus saith unto them, My meat is to do the will of him that sent me, and to accomplish his work. Say not ye, There are yet four months, and [then] cometh the harvest? behold, I say unto you, Lift up your eyes, and look on the fields, that they are white already unto harvest. He that reapeth receiveth wages, and gathereth fruit unto life eternal; that he that soweth and he that reapeth may rejoice together. For herein is the saying true, One soweth, and another reapeth. I sent you to reap that whereon ye have not labored: others have labored, and ye are entered into their labor. And from that city many of the Samaritans believed on him because of the word of the woman, who testified, He told me all things that [ever] I did. So when the Samaritans came unto him, they besought him to abide with them: and he abode there two days. And many more believed because of his word; and they said to the woman, Now we believe, not because of thy speaking: for we have heard for ourselves, and know that this is indeed the Saviour of the world." — John 4:28-42 (ASV)

And saith to the men, Come, see a man, which told me all things that ever I did: is not this the Christ? Then they went out of the city, and came unto Him. In the mean while his disciples prayed him, saying, Master, eat. But he said unto them, I have meat to eat that ye know not of. Therefore said the disciples one to another, Hath any man brought him ought to eat? Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work. Say not ye, There are yet four months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest. And he that reapeth receiveth wages, and gathereth fruit unto life eternal: that both he that soweth and he that reapeth may rejoice together. And herein is that saying true, One soweth, and another reapeth. I sent you to reap that whereon ye bestowed no labour: other men laboured, and ye are entered into their labours. And many of the Samaritans of that city believed on him for the saying of the woman, which testified, He told me all that ever I did.

Two days of Christ's personal ministry—what might not come of that?
