I don't disagree that we have a new identity and that we are changed. Praise the Lord for that! But answer me this: do you have a physical sinful body? Do you LIVE in that physical sinful body?
I live in a dead body born of the death of Adam. All sin has been condemned in it. Every vile deed known to mankind is it's habit. Now the good news,
Romans 8:10 ¶And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
11 But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
12 Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
17 ¶And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
18 For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.
19 For the earnest expectation of the creature waiteth for the manifestation of the sons of God.
20 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
