In verse 28 it tells us that with the return of the disciples, 'the woman left her waterpot, went her way into the city, and said to the men, "Come, and see a Man who told me all things that I ever did. Could this be the Christ?" This is not the same woman who came to the well a short while before. She was so excited about her encounter and His revelation to her that she left her waterpot sitting there and went straight into the city and she started telling the men of the city all about Him. I'll say again, "Not the same woman!" The shame that had her at the well alone during the hottest part of the day in order to avoid human contact? Gone! Now, instead of hiding she runs to the city and to the people with, "Come, and see a Man who told me all things that I ever did. Could this be the Christ?" She went from trying to deny her lifestyle to Jesus when He asked her to go get her husband to running to all the men of the city and declaring it to them with, "Come, and see a Man who told me all things that I ever did. Could this be the Christ?" Instead of avoiding she is now declaring, "He knew all the things I ever did, He knew my sin!" Her shame, GONE. Her excitement over who Jesus is now there for all the world to see.
For this woman, this Samaritan woman, this 'chance' encounter at the well had become for her a life changing one because from NOW on ...she was now free, free to worship in spirit and in truth with nothing to conceal!
