Our Lord here speaks of the second birth as completed by two agencies, water and the Spirit. To make the one of these merely the symbol of the other is to miss His meaning. The Baptist baptized with water for the remission of sins, but he was always careful to disclaim power to baptize with the Holy Ghost. His baptism with water was of course symbolical; that is to say, the water itself exercised no spiritual influence, but merely represented to the eye what was invisibly done in the heart. But that which it symbolised was not the life-giving influence of the Holy Spirit, but the washing away of sin from the soul. Assurance of pardon John was empowered to give. Those who humbly submitted to his baptism with confession of their sins went from it forgiven and cleansed. But more than that was needed to make them new men—and yet more he could not give. For that which would fill them with new life they must go to a Greater than he, who alone could bestow the Holy Ghost. These then are the two great incidents of the second birth—the pardon of sin, which is preparatory, and which cuts our connection with the past; the communication of life by the Spirit of God, which fits us for the future. Both of these are represented by Christian baptism because in Christ we have both; but those who were baptized by John’s baptism were only _prepared_ for receiving Christ’s Spirit by receiving the forgiveness of their sins. Having thus declared to Nicodemus the necessity of the second birth, He goes on to give the reason of this necessity. Birth by the Spirit is necessary, because that which is born of the flesh is flesh, and the kingdom of God is spiritual. Of course our Lord does not mean by flesh the mere tangible substance of the body; He does not mean that our first and natural birth puts us in possession of nothing but a material frame. By the word “flesh” He signifies the appetites, desires, faculties, which animate and govern the body, as well as the body itself—the whole equipment with which nature furnishes a man for life in this world. This natural birth gives a man entrance into much, and for ever determines much, that has important bearings on his person, character, and destiny. It determines all differences of nationality, of temperament, of sex; apart altogether from any choice of his it is determined whether he shall be a South Sea Islander or a European; an antediluvian living in a cave or an Englishman of the nineteenth century. But the kingdom of God is a spiritual kingdom, into which entrance can be had only by a man’s own will and spiritual condition, only by an attachment to God which is no part of a man’s natural equipment.
