He begins his gospel with a sublime assertion of the Deity and preëxistence of Christ as the Eternal Word, then tells of the incarnation, how the Word became flesh, and we beheld His glory, how although He was the Light of the world, yet the world knew Him not, and though He came unto His own (the Jews) yet His own received Him not, but as many as did receive Him, whether Jews or Gentiles, to them gave He power to become the children of God, and this through a new birth, not of human blood, or title, or pedigree, not of man in any way whatever, but of God. It is not sufficient, therefore, to be a child of God by creation, which, indeed, all men are, but by adoption, by the reception of the Divine nature by birth. And this new birth is more fully unfolded to the Jewish Sanhedrist, Nicodemus, both as to its necessity and its nature. "Ye must be born again." "The Son of man must be lifted up." The new birth is of water and the Spirit. The water is the water of life, the gospel offered freely to all, with its cleansing and refreshing and vivifying properties so well symbolized by water, and the Holy Spirit is the effective personal agent by whom the regeneration is wrought in the heart of the penitent sinner, though His operations may be as inexplicable as the wind, which bloweth where it listeth, and is known only by its results. Then we have the hinge-text of salvation, "God so loved the world that He gave His only begotten Son, that whosoever believeth in Him should not perish but have eternal life." Thus, in this marvelous discourse with Nicodemus, we have God's love or God's grace as the source of our salvation, Christ crucified as the ground of it, and the Holy Spirit as the Divine Agent of its accomplishment. Glory be to the Triune God. Not only the discourse of our Lord with Nicodemus on the new birth, but His discourse, also, with the woman of Samaria on true worship is given by John alone. It is remarkable that not to a Jewish Rabbi, not to the Scribes and Pharisees, not to a Jew at all, but to a heathen or semi-heathen woman, Jesus made the first recorded, positive declaration of His Messiahship, and showed her that as God is a Spirit, so they that worship Him must do so, not in any specific locality, such as Jerusalem or Mount Gerizim, and not by any prescribed form or any outward ritual, but in spirit and in truth. No wonder that her heart was immediately and completely captivated by so grand and glorious a revelation, and that, at once, she left her waterpot and went her way to become a preacher of righteousness to her fellow-townsmen.
