There was a man of the Pharisees, named Nicodemus, a ruler of the Jews [Judeans]:
The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
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 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, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit [spiritual water], he cannot enter into the kingdom of God.
That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Marvel not that I said unto thee, Ye must be born again.
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.
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost [Holy Spirit].
For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
…And the Lord added to the church daily such as should be saved.
Then Peter, filled with the Holy Ghost [holy spirit], said unto them, Ye rulers of the people, and elders of Israel.
Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.
Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
…call for Simon, whose surname is Peter;
Who shall tell thee words, whereby thou and all thy house shall be saved.
And as I began to speak, the Holy Ghost [holy spirit] fell on them, as on us at the beginning.
Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost [holy spirit].
Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?
When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life.
And brought them out, and said, Sirs, what must I do to be saved?
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
And they spake unto him the word of the Lord, and to all that were in his house.
And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway.
And when he had brought them into his house, he set meat before them, and rejoiced, believing in God with all his house.
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew [Judean] first, and also to the Greek [Gentile].
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.
For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
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.
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.
II Thessalonians 2:13:
But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth.
Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.
I Peter 1:23:
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
I John 5:13:
These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
