She approached to draw water from the well and saw Him sitting there. As she neared closer to the stranger He asked her for a drink. She wondered out loud, "How is it that you, a Jew, ask for a drink from me, a woman of Samaria?"
He was weary and thirsty, but it wasn't really about His need as much as it was about hers. She had a need but did not know the kind of need she had. She thought she simply needed the water from the well. If she had known what she really needed, and if she had known who He really was, she would have asked Him for a drink of His water-—the kind of water that, after you drink it, makes you never thirst again.
He knew she didn't know, so He made an offer. She inquired of Him concerning what He offered, and He told her about His living water. She asked Him for a drink, then He did it.
From her perspective, He didn't know her at all, yet He told her things about herself as if He knew her well. She wondered how He knew so much, and then He told her who He was. He gave her a drink, and, in a moment, her life was changed by the stranger who became her Savior.
(See John 4.)
I've been that thirsty woman; I've tasted that living water; and I've had that life changing moment with Him. That moment with Him that changes everything—it is the most important matter of the most important moment.
