2 Corinthians 5:17 ASV(17) Wherefore if any man is in Christ, he is a new creature: the old things are passed away; behold, they are become new.
Romans 12:1-2 ASV(1) I beseech you therefore, brethren, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service.(2) And be not fashioned according to this world: but be ye transformed by the renewing of your mind, that ye may prove what is the good and acceptable and perfect will of God.
John 3:3-8 ASV
(3) Jesus answered and said unto him, Verily, verily, I say unto thee, Except one be born anew, he cannot see the kingdom of God.
(4) Nicodemus saith unto him, How can a man be born when he is old? can he enter a second time into his mother's womb, and be born?
(5) Jesus answered, Verily, verily, I say unto thee, Except one be born of water and the Spirit, he cannot enter into the kingdom of God.
(6) That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
(7) Marvel not that I said unto thee, Ye must be born anew.
(8) The wind bloweth where it will, and thou hearest the voice thereof, but knowest not whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
