The law of the LORD [is] perfect, converting the soul: the testimony of the LORD [is] sure, making wise the simple.
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.
And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.
Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do [them].
A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
And I will give them an heart to know me, that I [am] the LORD: and they shall be my people, and I will be their God: for they shall return unto me with their whole heart.
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.
Marvel not that I said unto thee, Ye must be born again.
That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
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.
Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
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.
But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
1 John 5:1
Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
