14For by one offering he hath perfected for ever them that are sanctified. 15Whereof the Holy Ghost also is a witness to us: for after that he had said before, 16This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; 17And their sins and iniquities will I remember no more. 18Now where remission of these is, there is no more offering for sin. Hebrews 10: 14-17

But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; 12Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us. 13For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God? Hebrews 9: 11-14

8He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil. 9Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God. 1 John 3: 8-9

There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: 2The 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. 3Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. 4Nicodemus 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? 5Jesus 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. 6That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. 7Marvel not that I said unto thee, Ye must be born again. 8The 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. John 3: 1-8

And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. 18I will not leave you comfortless: I will come to you. John 14: 16-18
