John 3:5

Jesus answered, verily, verily, I say unto thee
Explaining somewhat more clearly, what he before said:

except a man be born of water and of the Spirit:
these are, (twnv) (twlm) , "two words", which express the same thing, as Kimchi observes in many places in his commentaries, and signify the grace of the Spirit of God. The Vulgate Latin and Ethiopic versions read, "the Holy Spirit", and so Nonnus; and who doubtless is intended: by "water", is not meant material water, or baptismal water; for water baptism is never expressed by water only, without some additional word, which shows, that the ordinance of water baptism is intended: nor has baptism any regenerating influence in it; a person may be baptized, as Simon Magus was, and yet not born again; and it is so far from having any such virtue, that a person ought to be born again, before he is admitted to that ordinance: and though submission to it is necessary, in order to a person's entrance into a Gospel church state; yet it is not necessary to the kingdom of heaven, or to eternal life and salvation: such a mistaken sense of this text, seems to have given the first birth and rise to infant baptism in the African churches; who taking the words in this bad sense, concluded their children must be baptized, or they could not be saved; whereas by "water" is meant, in a figurative and metaphorical sense, the grace of God, as it is elsewhere; see ( Ezekiel 36:25 ) ( John 4:14 ) . Which is the moving cause of this new birth, and according to which God begets men again to, a lively hope, and that by which it is effected; for it is by the grace of God, and not by the power of man's free will, that any are regenerated, or made new creatures: and if Nicodemus was an officer in the temple, that took care to provide water at the feasts, as Dr. Lightfoot thinks, and as it should seem Nicodemon ben Gorion was, by the story before related of him; (See Gill on John 3:1); very pertinently does our Lord make mention of water, it being his own element: regeneration is sometimes ascribed to God the Father, as in ( 1 Peter 1:3 ) ( James 1:18 ) , and sometimes to the Son, ( 1 John 2:29 ) and here to the Spirit, as in ( Titus 3:5 ) , who convinces of sin, sanctifies, renews, works faith, and every other grace; begins and carries on the work of grace, unto perfection;

he cannot enter into the kingdom of God;
and unless a man has this work of his wrought on his soul, as he will never understand divine and spiritual things, so he can have no right to Gospel ordinances, or things appertaining to the kingdom of God; nor can he be thought to have passed from death to life, and to have entered into an open state of grace, and the kingdom of it; or that living and dying so, he shall ever enter into the kingdom of heaven; for unless a man is regenerated, he is not born heir apparent to it; and without internal holiness, shall not enter into it, enjoy it, or see God.
