Listening to the Word [Jesus] is God's will but so also is acting after hearing. She proclaims to the people of the city that He has supernaturally told her about her deepest secrets and hurts; that the Messiah is by the well. Jesus reveals to the disciples, in the meantime, that although His body is weary for water and food His true food is to do the will of the Father. In that, Christ finds His sustenance. And that's true for us. Man shall not live by bread alone but by every Word of God. And that Word is His will. This moment is an example to all followers of Christ. We will find our true purpose, pleasure, and sustenance in doing the will of God. Forsaking natural and carnal impulses for the desires of God is what's characteristic of the believer. Jesus wants them to wake up and look around. The harvest of eternal life is upon them; the Messianic age of sowing and reaping is here and now… it's time for them to eat their true food and get to work. The people of Samaria come out and ask Jesus to stay with them. Now upon His Word they believe He is the Savior of the world. And that's the point John is making in sharing this account: Jesus is not just a Savior of Jews, He is the Savior from the Jews, who saves Jews, Samaritans and even those to the ends of the earth.
