2 Corinthians 5:17-21 (King James Version)

17Therefore if any man be in Christ, he is a new creature: old things are
passed away; behold, all things are become new.

18And all things are of God, who hath reconciled us to himself by Jesus
Christ, and hath given to us the ministry of reconciliation;

19To 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.

20Now 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.

21For he hath made him to be sin for us, who knew no sin; that we might be
made the righteousness of God in him.

1 John 1:2 (King James Version)

(For the life was manifested, and we have seen it, and bear witness, and
shew unto you that eternal life, which was with the Father, and was
manifested unto us;)

1 John 1:9 (King James Version)

If we confess our sins, he is faithful and just to forgive us our sins, and
to cleanse us from all unrighteousness.

Ephesians 2:5-6 (King James Version)

5Even when we were dead in sins, hath quickened us together with Christ, (by
grace ye are saved;)

6And hath raised us up together, and made us sit together in heavenly places
in Christ Jesus:

Colossians 1:13-14 (King James Version)

13Who hath delivered us from the power of darkness, and hath translated us
into the kingdom of his dear Son:

14In whom we have redemption through his blood, even the forgiveness of
sins:

Romans 8:3-4 (King James Version)

3For what the law could not do, in that it was weak through the flesh, God
sending his own Son in the likeness of sinful flesh, and for sin, condemned
sin in the flesh:

4That the righteousness of the law might be fulfilled in us, who walk not
after the flesh, but after the Spirit.

1 John 1:7 (King James Version)

But if we walk in the light, as he is in the light, we have fellowship one
with another, and the blood of Jesus Christ his Son cleanseth us from all
sin.

1 John 3:6-10 (King James Version)

6Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him,
neither known him.

 7Little children, let no man deceive you: he that doeth righteousness is
righteous, even as he is righteous.

 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.

 10In this the children of God are manifest, and the children of the devil:
whosoever doeth not righteousness is not of God, neither he that loveth not
his brother.

Hebrews 10:1-2 (King James Version)

1For the law having a shadow of good things to come, and not the very image
of the things, can never with those sacrifices which they offered year by
year continually make the comers thereunto perfect.

2For then would they not have ceased to be offered? because that the
worshippers once purged should have had no more conscience of sins.

Hebrews 10:12-14 (King James Version)

12But this man, after he had offered one sacrifice for sins for ever, sat
down on the right hand of God;

13From henceforth expecting till his enemies be made his footstool.

14For by one offering he hath perfected for ever them that are sanctified.

John 1:12 (King James Version)

But as many as received him, to them gave he power to become the sons of
God, even to them that believe on his name:

Ephesians 4:22-25 (King James Version)

22That ye put off concerning the former conversation the old man, which is
corrupt according to the deceitful lusts;

23And be renewed in the spirit of your mind;

24And that ye put on the new man, which after God is created in
righteousness and true holiness.

25Wherefore putting away lying, speak every man truth with his neighbour:
for we are members one of another.
