In this text Jesus' motive is so very clear, "My food is to do the will of Him who sent Me, and to finish His work." (4:34) The will of the Father was literally His nourishment and sustenance. Keeping His gaze set on the Giver of life was His life. And coming into contact with Him spurred spiritual awakening.
He seeks out this Samaritan woman--seemingly defiled if you ask any Jew. And He purposefully converses with her, aiming to point her to truth. He tells her that the Father is seeking true worshippers. Wait a minute, the Father is seeking?! Just think about that. The Father seeks after worshippers. He sought after you. He sought after me. How humbling.
Once she finally "gets it" she runs into the city to tell everyone that she just met the Messiah; and many believe because of her testimony. (4:39) "Evangelism" of the overflow will draw many. Does that make sense? As we truly meet with Christ--as we "get it"--our natural response will be to tell others. He is just that good.
In this day, Lord, enable us to keep our eyes on your will in the moments--the difficult, exciting, lonely, full, messy moments.
