Why do we sin if we have a new Nature in the image of God

 Why do we sin if we have a new nature???

Colos 3:10

1 If then you have been raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God. 2 Set your minds on things that are above, not on things that are on earth. 3 For you have died, and your life is hid with Christ in God. 4 When Christ who is our life appears, then you also will appear with him in glory. 5 Put to death therefore what is earthly in you: fornication, impurity, passion, evil desire, and covetousness, which is idolatry. 6 On account of these the wrath of God is coming. 7 In these you once walked, when you lived in them. 8 But now put them all away: anger, wrath, malice, slander, and foul talk from your mouth. 9 Do not lie to one another, seeing that you have put off the old nature with its practices 10 and have put on the new nature, which is being renewed in knowledge after the image of its creator. RSV

9 Do not lie to one another, seeing that you have put off the old self with its practices 10 and have put on the new self, which is being renewed in knowledge after the image of its creator. ESV

 9 Do not lie to each other, since you have taken off your old self with its practices 10
and have put on the new self, which is being renewed in knowledge in the image of its Creator.
NIV
9 Don’t lie to each other, for you have stripped off your old sinful nature and all its wicked deeds. 10 Put on your new nature, and be renewed as you learn to know your Creator and become like him. NLT

Other versions use old man , new man, its all the same from what I can see. So if the old man,old self ,old nature was crucified ,done away with (NASB)  and we have a new self  ,a new man, a new nature ,in the image of God ,Creator ,Jesus Then why do Christians sin. The two natures can not co -exist in the believer , That would be like serving  two masters, that would also give us duel natures. That's not possible,light and dark cannot dwell in the same place at the same time. A little hint as to the direction I'm headed  how about sinful flesh yes our flesh  ( GR Sarks=Flesh)its the only part of the human body that continues to be in the penalty for sin as it decays daily, Not until after we die and are resurrected will our flesh be renewed.

So we shall continue look at Romans 6:6-7( read all of  Romans 6:1-14)

Romans 6

6 We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. 7 For one who has died has been set free from sin.RSV

6 We know that our old self was crucified with him so that the sinful body might be destroyed, and we might no longer be enslaved to sin. 7 For he who has died is freed from sin.ESV
The Greek here is Soma not Sarks ,soma is body or members, sarks is flesh

6 We know that our old sinful selves were crucified with Christ so that sin might lose its power in our lives. We are no longer slaves to sin. 7 For when we died with Christ we were set free from the power of sin. NLT
6 For we know that our old self was crucified with him so that the body ruled by sin might be done away with , that we should no longer be slaves to sin 7 because anyone who has died has been set free from sin. NIV

In  verse 7 the word body is being used (Grk soma) This could be interpreted  two ways body as in a physical body or body like a body of water,like sin as a mass ,probably means physical body. Seen as the place were sin ruled .My Key Word Study Bible  (NKJV) has the Greek and Hebrew words in it  Interprets  soma in this use as body : Spoken of the seat of sinful affections and appetites. With the old nature being brought to nothing so that sin no longer has a seat in the body.I think the NLT and yes I know its a paraphrase ,yet I like how its put . "Romans 6:We know that our old sinful selves were crucified with Christ so that sin might lose its power in our lives. We are no longer slaves to sin." With the old nature crucified and sin not having a seat in the body, then why do we still sin?  Its not in our nature because we have a Christ like nature,Colos 3:9-10 :Do not lie to one another, seeing that you have put off the old nature with its practices and have put on the new nature, which is being renewed in knowledge after the image of its creator.   Jesus is our creator so our new nature is being renewed into his image. As I stated earlier we can't have duel natures its either sinful nature or a Christ like nature   being renewed in the knowledge of our Creator to be more like Him. I don't think

I could be any clearer about my thoughts on  Christians having a sinful nature, I just don't see it. So time to look at the flesh and there a a plethora of scripture that speaks about the sinful flesh or the desires of the flesh. So time to dig in.   

Romans 7

21 So I find it to be a law that when I want to do right, evil lies close at hand. 22 For I delight in the law of God, in my inmost self, 23 but I see in my members another law at war with the law of my mind and making me captive to the law of sin which dwells in my members. 24 Wretched man that I am! Who will deliver me from this body of death? 25 Thanks be to God through Jesus Christ our Lord! So then, I of myself serve the law of God with my mind, but with my flesh I serve the law of sin. RSV

. 21 So I find it to be a law that when I want to do right, evil lies close at hand. 22 For I delight in the law of God, in my inner being, 23 but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. 24 Wretched man that I am! Who will deliver me from this body of death? 25 Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin. ESV

 21 So I find this law at work: When I want to do good, evil is right there with me. 22 For in my inner being I delight in God's law; 23 but I see another law at work in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin at work within my members. 24 What a wretched man I am! Who will rescue me from this body of death?  25 Thanks be to God, who delivers me through Jesus Christ our Lord!
So then, I myself in my mind am a slave to God’s law, but in my sinful nature a slave to the law of sin.NIV

21 It seems to be a fact of life that when I want to do what is right, I inevitably do what is wrong. 22 I love God's law with all my heart. 23 But there is another law at work within me that is at war with my mind. This law wins the fight and makes me a slave to the sin that is still within me. 24 Oh, what a miserable person I am! Who will free me from this life that is dominated by sin? 25 Thank God! The answer is in Jesus Christ our Lord. So you see how it is: In my mind I really want to obey God’s law, but because of my sinful nature I am a slave to sin.  NLT

Wow I really don't care for the NIV rendering of this scripture  and I'm done using the NLT  ,I although Christians fail and sin ,if the Christian life is dominated by sin as the NLT puts vs 24 " this life that is dominated by sin? "then are they really Christians ? maybe I'm going to an extreme ,just my opinion. and again the Grk is Sarx =Flesh The NIValso translates Sarx as nature.

The body is dead because of sin there is no rescue for it until resurrection Romans 8:10 But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness. 11 If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.

 Using Blue Letter Bible searching ability's out of fourteen different translations sin nature only appears in two of the fourteen . Can you guess what two translations use sin nature or sinful nature ?

Give up ? The NIV and NLT  the rest KJV ,NKJV ,ESV, HCSB, NASB, RSV,ASV, YLT, DBY, WEB, HNV, and the Latin Vulgat all interpret Sarks as Flesh .Does that make you possibly think that nature is an incorrect translation of the word  Grk Sarks..

In the better translations nature is not used when talking about sin. I'm not going to copy and past all the verses that use flesh when talking about sin .I think the promotion of a sinful nature was brought on by bad translations of the Bible ( such as NIV,  NLT and probably any other that uses modern English)  I'm going to end this with some thought from John MacArthur HIS ONE NATURE POSITION

"Salvation is not a matter of improvement or perfection of what has previously existed. It is total transformation...At the new birth a person becomes `a new creature; the old things passed away; behold, new things have come' (2 Cor. 5:17). It is not simply that he receives something new but that he becomes someone new...The new nature is not added to the old nature but replaces it. The transformed person is a completely new `  Biblical terminology, then, does not say that a Christian has two different natures. He has but one nature, the new nature in Christ. The old self dies and the new self lives; they do not coexist. It is not a remaining old nature but the remaining garment of sinful flesh that causes Christians to sin. The Christian is a single new person, a totally new creation, not a spiritual  *schizophrenic...The believer as a total person is transformed but not yet wholly perfect. He has residing sin but no longer reigning sin. He is no longer the old man corrupted but is now the new man created in righteousness and holiness, awaiting full salvation." (The MacArthur New Testament Commentary-EPHESIANS, p. 164)

"The believer does not have two competing natures, the old and the new; but one new nature that is still incarcerated in un-redeemed flesh" [Study Bible Note under Romans 6:6].

"Explaining the reality that the believer has only one new nature is not simply playing a psychological word game. It isn't saying to yourself, `I'm really wonderful, holy, and righteous', until you finally convince yourself of something that isn't true. The point is that God's Word teaches that sin's power is broken in the life of the believer, and our response is to believe that to be true" (Freedom From Sin, p. 52).

"Nor is Paul describing a dualistic, *schizophrenic Christian...Christians sin because of the vestiges of sinful flesh, not because they have the same old active sinful nature. Certainly we sin, but when we sin it is contrary to our nature, not because we have two dispositions—one sinful and one not" (Faith Works, p. 116).

"If you are a Christian, it's a serious misunderstanding to think of yourself as having both an old and new nature. We do not have a dual personality! Assuming the dual nature of the believer could easily lead one to excuse all kinds of sins by blaming them on the old nature" ("The Good Natured Believer" by John MacArthur in The Masterpiece magazine, March/April 1990, p. 18).

"I know of a pastor who counsels premarital couples to take a shower together. He tells them not to worry about sin, saying that when we sin, it is simply a manifestation of our old nature. He believes the old nature is going to sin anyway, so there's nothing believers can do about it. But according to the Apostle Paul, the believer's old nature is dead and buried. With that in mind, how can we possibly serve sin? Those who hold the view that sees a dual nature in the believer could easily attempt to excuse all kinds of sins by blaming them on the old nature" (Freedom From Sin, p. 31; 

"Salvation is a spiritual union with Jesus Christ in His death and resurrection that can also be described as the death of the `old self' and the resurrection of the `new self,' who now walks in `newness of life.' This union and new identity clearly means that salvation is transformation. It is not addition of a new self to an old self. In Christ, the old self no longer exists (compare 2 Cor. 5:17)." (EPHESIANS, p. 177)

 *Definition of schizophrenia in English:

noun

1A long-term mental disorder of a type involving a breakdown in the relation between thought, emotion, and behavior, leading to faulty perception, inappropriate actions and feelings, withdrawal from reality and personal relationships into fantasy and delusion, and a sense of mental fragmentation.

Well that's it I'm done  I feel we do not have a sin nature  we have unregenerated flesh ,Flesh that is still corrupt ,still decaying ,still serving the penalty of sin,still in sin, Still will die(unless the rapture is correct then maybe not)Christians sin because they fail to do what the bible say's 

Romans 8:1-4

1 There is therefore now no condemnation for those who are in Christ Jesus. 2 For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. 3 For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, 4 in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit
