Marvel not that I said unto you, You must be born again.

John Chrysostom
AD 407
For by saying, Marvel not, He indicates the confusion of his soul, and leads him to something lighter than body. He had already led him away from fleshly things, by saying, That which is born of the Spirit is spirit; but when Nicodemus knew not what that which is born of the Spirit is spirit meant, He next carries him to another figure, not bringing him to the density of bodies, nor yet speaking of things purely incorporeal, (for had he heard he could not have received this,) but having found a something between what is and what is not body, namely, the motion of the wind, He brings him to that next. And He says of it,
You hear the sound thereof, but canst not tell whence it comes, and whither it goes.
Though He says, it blows where it lists, He says it not as if the wind had any power of choice, but declaring that its natural motion cannot be hindered, and is with power. For Scripture knows how to speak thus of things without life, as when it says, The creature was made subject to vanity, not willingly. Romans 8:20 The expression therefore, blows where it lists, is that of one who would show that it cannot be restrained, that it is spread abroad everywhere, and that none can hinder its passing hither and there, but that it goes abroad with great might, and none is able to turn aside its violence.
2. And you hear its voice, (that is, its rustle, its noise,) but canst not tell whence it comes, and whither it goes; so is every one that is born of the Spirit.
Here is the conclusion of the whole matter. If, says He, you know not how to explain the motion nor the path of this wind which you perceive by hearing and touch, why are you over-anxious about the working of the Divine Spirit, when you understand not that of the wind, though you hear its voice? The expression, blows where it lists, is also used to establish the power of the Comforter; for if none can hold the wind, but it moves where it lists, much less will the laws of nature, or limits of bodily generation, or anything of the like kind, be able to restrain the operations of the Spirit.
That the expression, you hear its voice, is used respecting the wind, is clear from this circumstance; He would not, when conversing with an unbeliever and one unacquainted with the operation of the Spirit, have said, You hear its voice. As then the wind is not visible, although it utters a sound, so neither is the birth of that which is spiritual visible to our bodily eyes; yet the wind is a body, although a very subtle one; for whatever is the object of sense is body. If then you do not complain because you cannot see this body, and do not on this account disbelieve, why do you, when you hear of the Spirit, hesitate and demand such exact accounts, although you act not so in the case of a body? What then does Nicodemus? Still he continues in his low Jewish opinion, and that too when so clear an example has been mentioned to him. Wherefore when he again says doubtingly,
