Nicodemus: "Jesus, how can a man be born again?"
Jesus: "The Spirit moves wherever it wants. All you can see, is the result."
I think that is pretty clear. Doesn't require any explanation.
Notice you said, "I think". You didn't show scripture. Let's look at the verses and see what it actually says.
John 3:5 Jesus 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.
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7 Marvel not that I said unto thee, Ye must be born again.
8 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.
In verse 5 Jesus says a man must be born of water and of the Spirit to enter the kingdom of God, so it is not only the Spriit that is necessary, it is also the water.
Now what is this water? There are many opinions on this, but I personally believe this is speaking of the word of God.
Eph 5:26 That he might sanctify and cleanse it with the washing of water by the word,
1 Pet 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
This verse is very important, because it specifically says we are born again "by the word of God". So, I personally believe the water spoken of in John 3:5 is the word of God. Without first hearing the word of God you cannot be born again.
Verse 6 shows that a spiritual birth is required to enter the kingdom of God.
Now, look carefully at verse 8, what does it say? Jesus compares the Holy Spirit to the wind. We cannot see the wind, but notice carefully Jesus says, "thou hearest the sound thereof". No regeneration mentioned here, the one and only effect shown is that we can hear the Spirit. Now how do you hear the Spirit?
Let me ask you, did you hear the sound of the Holy Spirit when you were regenerated? I did. I heard the preaching of the word of God which convicted me as a sinner, but also taught me that Jesus died for my sins and would save me if I came to him in repentance.
I cannot explain this because it is supernatural, but the scriptures are the power of the Spirit of God. The word of God is quick and powerful and able to pierce to the heart.
Heb 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
Faith comes by hearing the word of God. Notice that Paul does not say faith comes by the regeneration of the Holy Spirit. Did Paul forget to mention this? It is hard to believe Paul could overlook such an important doctrine. But if you believe Calvinism you must believe Paul failed to mention one of the most important doctrines you hold, and says we must only hear the word of God to have faith.
Rom 10:17 So then faith cometh by hearing, and hearing by the word of God.
The scriptures numerous times show we receive the Holy Spirit by hearing and believing God's word.
Gal 3:2 This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith?
I mean, there it is right there, Paul says we received the Spirit by the hearing of faith. So faith precedes regeneration. And there are other verses that show this.
Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
The order of events in salvation is very clearly shown here, #1 a man hears the gospel, #2 a man trusts or believes the gospel, and #3 a man receives and is sealed by the Holy Spirit.
Now, I have shown scripture, not personal opinion, and I can show many more. You cannot show one single verse to support that the Holy Spirit regenerates a man to have faith. In hundreds of years not one Calvinist has ever been able to show this. No, you read into the scriptures what you want them to say to validate your doctrine, but they do not.
John 3 does not say a man is regenerated to have faith, in fact, the only effect shown is that a man hears the sound thereof. That's it.
