The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit (John 3:8) KJV

The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit. (John 3:8) NKJV

This verse is about the wind and not about us. The verse suggests that the process of spiritual rebirth is an unseen thing which is related to God who is unseen – so that those watching cannot see the origin of the Spirit and the change wrought in the man.  The invisible God is naturally the source of spiritual rebirth – but he has set the criteria for when the spiritual rebirth occurs. Being born of God comes as a result of the spiritual rebirth, and the Bible says that when we come to God we must believe that our seeking will result in the encounter we seek – a close relationship with Jesus Christ and a transformed life – which is an unseen process LIKE THE WIND! We can’t see the wind directly, but indirectly we can see what the wind can do – when it blows through trees/bushes and when it moves loose objects on the ground.

Hebr. 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

This does not indicate that the spiritual rebirth happens out of the blue disconnected to any seeking on the part of the new Christian.  Calvinism, on the other hand, reverses the process of rebirth which is fatal, because it exempts human beings from the responsibility to seek and find God – since God does all this for them (if they are elect). God, in his kindness, responds to honest humble seeking on the part of a broken man, and he calls the lost for repentance. Those who are NOT lost don’t need to repent (the case could be that they have already repented for their sins), and again Jesus did not call that category –  the “non-lost” christians – to repentance but only the lost individuals! This totally refutes the calvinistic idea that Jesus died only for the elect, because the true christians here must surely be those that have repented for their sins and become cleansed in the blood of Jesus, and we can read in these verses that Jesus did not call them for repentance, but all OTHERS. The reason why he call all others for repentance, is because the others are already on safe ground.

Luke 15:7 I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.

Matt. 9:13 But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.

Man cannot find God without him  first having revealed himself to man, and he certainly has.

John 1:4 In him was life; and the life was the light of men.—8 He was not that Light, but was sent to bear witness of that Light.9 That was the true Light, which lighteth every man that cometh into the world.

Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.22 Professing themselves to be wise, they became fools,23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things. 

Acts 17:26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:

It’s certainly true that we can’t enter the kingdom of God unless we are born again (from God who is above), and that’s why we should seek God, repent for our sins in order to be cleansed and become new persons. God did not send his son to condemn the world, but to SAVE the world, and he doesn’t want anyone to perish. However, he is not going to force us to confess our sins and repent, but he influences us by sending out prophets (as in the old testament) and his WORD in the gospel, with the hope that as many as possible will choose to come to him to get life. The context:

John 3:⁵Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. ⁶That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. ⁷Marvel not that I said unto thee, Ye must be born again. ⁸The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit. ⁹Nicodemus answered and said unto him, How can these things be? ¹⁰Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? ¹¹Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. ¹²If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things? ¹³And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. ¹⁴And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: ¹⁵That whosoever believeth in him should not perish, but have eternal life. ¹⁶For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. ¹⁷For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
