Required to be born again, here are all born again verses for you, it is called looking forward pressing forward towards Christ ( not backwards into disbelief which is sin:
Romans 14:23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
That is not how we are born again and that verse has nothing to do with salvation.
Your reference below does. Note the emboldened portion of that reference that it is by believing n Him, even in His name, is how we are saved.
John 1:12 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:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Salvation is no by the will of man nor by the will of the flesh
Your reference below leaves much out on how one is born again.
John 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Nicodemus asked Jesus this question of how this can come about and Jesus explained to him that after His ascension which is after His crucifixion, anyone that believes in Him will be saved.
John 3:9 Nicodemus answered and said unto him, How can these things be? 10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? 11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. 12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. 14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: 15 That whosoever believeth in him should not perish, but have eternal life. 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
Discipleship is separate from salvation; Jesus warned that not every believer that receives the seed will bear fruit.
1 John 3: 9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
1 John 5:18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
The apostle John was addressing believers that were believing that sin was no longer sin to them and that they could live in sin for why he was correcting them that we are to walk in the light in fellowship with the Father & the Son as we are to confess our sins if we commit them.
To imply that we can never sin is denying the Lord's prayer we are to pray daily.
Some ( Christians forsaken the right way/false teachers as told) have ceased from sin,m some CANNOT CEASE FROM SIN..
1 Peter 4:1 Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin;
2 Peter 2:14 Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:
15 Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness;
I agree but not every believer has been discipled, taught in the word to bear fruit so that their joy may be full. Some sow to the flesh foolishly in reaping corruption while others are offended by the scripture in the ace of the evolution theory for why some no longer believe. Some worry in the face of the cares of this life for why they do not bear fruit but none of these negates their salvation; but they are at risk of being denied by Him unless they repent before the Bridegroom comes by looking to the author & finisher of our faith to help us lay aside every weight & sin daily per Hebrews 12:1-2.
So there is a race to be run by faith in Jesus Christ in helping us to follow Him as this involves laying aside every weight & sin daily.
To say that a believer can never sin again after they have been saved is denying the Lord's prayer.
No one will believe you that you have never sinned after salvation. Putting off doing a good deed is sin and not just making boastful plans for tomorrow.
James 4:13 Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain: 14 Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. 15 For that ye ought to say, If the Lord will, we shall live, and do this, or that. 16 But now ye rejoice in your boastings: all such rejoicing is evil.
17 Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
Your emphasis on the believer to never sin in order to be born again and thus saved is void of our hope in Christ for following Him as well as denying Him that we are saved simply by believing in Him as the scripture plainly testifies. Discipleship is required for bearing fruit; not for obtaining salvation.
