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.
If this passage is referring to the spiritual birth from above, which I'm not convinced that it is, it is not from the preached word or from the written word, it is the living Word. Christ, the life giving Spirit.
No matter what you say, if one is not born again by the word of God, then he is not born again at all.
Correct me if I'm wrong, I'm supposing that what you mean here is belief of the gospel gets one born from above. If so, you have inserted the gospel into the context of Jn 3:5, and it ain't there. And it confines the Spirit to only wherever men may carry the gospel which is contradictory of the 8th verse, “the Spirit where he willeth doth blow. Man doesn't convey the Spirit. The Spirit goes wherever He wills. John 3:3-8 is about regeneration, not conversion. The consistent order given in the scripture is the spiritual birth first, then conversion.
Observe:
But he that doeth the truth cometh to the light, that his works may be made manifest, that they have been wrought in God. Jn3:21
God has wrought in these prior to them 'coming to the light'. That's why they come to the light, because God has wrought. It's the spiritual birth first, then conversion.
Another (there's several once you acquire an eye for it):
Jesus saw Nathanael coming to him, and saith of him, Behold, an Israelite indeed, in whom is no guile! Jn 1:47
An Israelite indeed Christ called him, and that before Nathanael had ever met Christ. Romans 2:29:
'but he is a Jew who is one inwardly; and circumcision is that of the heart, in the spirit not in the letter; whose praise is not of men, but of God.'
“Whose praise is not of men, but of God”. Christ praised Nathanael, “Behold, an Israelite indeed, in whom is no guile!”. It's the spiritual birth first, then conversion.
Another:
Christ commissioning the Twelve and sending them forth (Mt 10, Lk 10), He instructs them to go to the lost sheep (not goats) (as in Ezek 34), and search for those worthy, and for those sons of peace:
“...whatsoever city or village ye shall enter, search out who in it is worthy...”
“....if a son of peace be there, your peace shall rest upon him....”
They were 'worthy sons of peace' prior to hearing and believing the gospel. It's the spiritual birth first, then conversion.
Another:
“He that believeth on the Son hath eternal life;......” Jn 3:36
“.....He that heareth my word, and believeth him that sent me, hath eternal life,...” Jn5:24
“... He that believeth hath eternal life.” Jn 6:47
Those that believe have already been born from above and have eternal life. It's the spiritual birth first, then conversion.
Another:
....Cornelius...a devout man...that feared God...who gave much...and prayed... Acts 10:1,2
And that before Peter had ever preached the gospel to Cornelius. It's the spiritual birth first, then conversion.
Another:
for not the hearers of the law are just before God, but the doers of the law shall be justified: (for when Gentiles that have not the law do by nature the things of the law, these, not having the law, are the law unto themselves; in that they show the work of the law written in their hearts, their conscience bearing witness therewith, and their thoughts one with another accusing or else excusing them); Ro 2:13-15
Not 'the hearers' of the law, but 'the doers' of the law are just before God.
Ro 13:10:
“Love worketh no ill to his neighbor: love therefore is the fulfilment of the law”
Charitable Cornelius showed the work of the law written in his heart, as I'm certain multitudes of Gentiles that had not the law had done down through the ages before him. The Spirit blows where it wills.
The Word of God is the agent by which a person is born again.
The gospel is not the means by which man is born from above. It's the spiritual birth first, then conversion.
The Lord uses the Holy Spirit in addition to that as John 3:5 tells us.
IN ADDITION TO?!? WOW !! I wonder how many that hold to baptismal regeneration have said the same exact thing. The 'addition' here is your forcing of the gospel into v 5. Absolutely no different from them that force the passage to mean water baptism.
John 1:12,13 tells us that receiving Christ by faith or believing on Him is absolutely imperative to be one of His children.
V 13 is very plain that those that did receive Him had already been born of God, and contains a threefold denial of any human involvement in that birth. It's the spiritual birth first, then conversion.
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: (John 1:12)
--How do you become a child of God (born again)?
You believe on his name! That is the answer in the verse.
It is asked and answered in the same verse.
God has given man a free will: whether to believe or not to believe on Christ. Man has that choice.
A child of God by name or practically, not positionally. They were already His sheep, albeit lost sheep until now.
