Must be born again by the incorruptible seed which is the words the LORD pronounced with his lips and preserved for every generation
For all have sinned, and come short of the glory of God;
For when ye were the servants of sin, ye were free from righteousness.
 What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death.
 But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
 If then I do that which I would not, I consent unto the law that it is good.
 Now then it is no more I that do it, but sin that dwelleth in me.
 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
 For the good that I would I do not: but the evil which I would not, that I do.
 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
 I find then a law, that, when I would do good, evil is present with me.
 For I delight in the law of God after the inward man:
 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
 O wretched man that I am! who shall deliver me from the body of this death?
 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
Finally, my brethren, rejoice in the Lord. To write the same things to you, to me indeed is not grievous, but for you it is safe.
 Beware of dogs, beware of evil workers, beware of the concision.
 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
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.
1 Peter 1:23
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
Now the parable is this: The seed is the word of God.
My covenant will I not break, nor alter the thing that is gone out of my lips.
Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures.
That we should be to the praise of his glory, who first trusted in Christ.
 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,
But if ye be led of the Spirit, ye are not under the law.
For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:  But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
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.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
 Not of works, lest any man should boast.
 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
So then faith cometh by hearing, and hearing by the word of God.
Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
