Ezek 36:25-27 (KJV) ¶Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you. 26 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. 27 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.

John 3:3-6 (KJV) 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." 4 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? 5 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." 6 "That which is born of the flesh is flesh; and that which is born of the Spirit is spirit."

John 3:16-18 (KJV) "¶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."

II Corinthians 5:17-21 (KJV) Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. 18 And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation; 19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation. 20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God. 21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.

John 14:6 (KJV) Jesus saith unto him, "I am the way, the truth, and the life: no man cometh unto the Father, but by me."
