God created everything good. And while God, alone, is perfect in the infinite and absolute sense, all created beings have their own nature which is common to their species, and is "perfect" for that being's intended purpose. We share our human nature with Adam, and it didn't change with the Fall.
I don't know why you don't see that sin [singular] as a nature,
entered into the world and damaged the God made humanity.
You have an unfallen man - Adam, before he ate of the forbidden fruit.
Then you have the fallen man - Adam, after he disobeyed God and ate.
The nature of sin in the flesh entered the world not through the one Creator God.
It entered through the disobedience of one man - Adam.
Therefore just as through one man sin entered into the world, (Rom. 5:12a)
This is something of a law in the members of our body and "dwells" in man.
Now then it is no longer I that work it out but sin that dwells in me.
For I know that in me, that is, in my flesh, nothing good dwells;
for to will is present with me, but to work out the good is not. (Rom. 7:17,18)
But I see a different law in my members, warring against the law of my mind
and making me a captive to the law of sin which is in my members.
Wretched man that I am! Who will deliver me from the body of this death? (.vs. 23,24)
Can't you feel the kindof "itchy" feeling in your members of your body urging you
to use them for sinning?
There's nothing innately wrong with the "flesh", and God commands nothing which isn't possible to obey. The problem is when human flesh is on its own, apart from the divine, which man is not meant to be apart from. Adam thought otherwise, but, "Apart from Me you can do nothing" (John 15:5).
So man from Adam's fall was sent out and away from the presence of God and from the right to
the tree of life which in his neutral state he had not yet eaten.
Fallen man was
"alienated from the life of God". (Eph. 4:18)
The fallen man "estranged [or alienated]" not only from God from "the life of God"
has the Satanic spirit of the air operating in him making him by nature children of God's wrath.
In which you once walked according to the age of this world, according to the ruler of the authority of the air, of the spirit which is now operating in the sons of disobedience;
Among whom we also all conducted ourselves once in the lusts of our flesh, doing the desires of the flesh and of the thoughts, and were by nature children of wrath, even as the rest; (Eph. 2;2,3)
I said there was an unfallen nature in Adam.
And after his disobedience a sin nature in Adam.
When the Son of God incarnated to be a man He came in the likeness of the fallen man.
He had not the sin in the flesh. But He came in the likeness of that damaged man.
God, sending His own Son in the likeness of the flesh of sin and concerning sin, condemned sin in the flesh, (Rom. 8:3)
Did you notice that? It says
"the flesh of sin".
God created a body for Adam. God did not create "the flesh of sin" for Adam.
That Adam received when he ate the forbidden fruit. Sin entered the world FIRST through Adam right into his transmuted body into
the flesh of sin. It passed on to all mankind.
Jesus came in the
likeness of the man with the
"flesh of sin" yet without sin.
So Jesus came to reconcile man with God in order to restore that union, a union which He, as the only begotten Son of God, experienced by virtue of who He is and which we were created to experience by virtue of God's plan for man, who we are. Christ is our model.
Why doesn't the
Gospel of John merely repeat that Jesus is our "model" then?
Now I agree that Jesus is a model. But more so He can be imparted INTO man as divine ZOE life.
That is the very life of God from which we were alienated
(Eph. 4:18) now through Christ can come INTO us.
In Him was life, and the life was the light of men. (John 1:4)
John did not just say "in Him we have a model."
I have come that they may have life and may have it abundantly. (John 10:10)
You see He did not come merely to give us an outward model to imitate - not without His very life within.
But these have been written that you may believe that Jesus is the Christ,
the Son of God, and that believing, you may have life in His name. (John 20:31)
He Himself with His Father come as the divine "We" to live within and make an abode within His lovers.
Jesus answered and said to him, If anyone loves Me, he will keep My word, and My Father will love him, and We will come to him and make an abode with him. (John 14:23)
Adam, our former model, didn't need to be a sinner first but, as a created being, he already inherently lacked the absolute perfection of God, meaning that he could err, he could choose foolishly, abusing the good gift of free will that is exclusive to men and angels. And that's what he did.
He not only disobeyed and committed that transgression. He ate something which somehow joined him to Satan.
And through this sin in the flesh entered into the world first into Adam and passed on to all his descendents - all mankind.
You see it says this happened through the disobedience
"the body of sin" (Rom. 6:6)
and
"the body of this death" (Rom. 7:24) came about for all mankind.
By his act of disobedience his world changed,
On this we agree.
no longer aligned with and subservient to God in the spiritual and moral sphere.
This is true.
But it is the warring of the sin in the flesh against the soul which commenced for all men after Adam ate.
Beloved, I entreat you as strangers and sojourners to abstain from fleshly lusts, which war against the soul, (1 Pet. 2;11)
Adam had become his own "god" for all practical purposes,
True. With Satan operating in him and a wretched
body of this death.
in control of determining morality for himself, not answerable to God. And from there, from that position, sin would flourish in his brave new world where mans will reigns.
Adam gained the knowledge of good and evil.
Adam lost the power to perform the good that he knows.
Adam lost the power to resist the evil that he knows.
This was the emmergence of something called
"the old man".
And by the power of being immersed into Christ (not just as ritual) the killing power of Christ's death
can terminate in us
"the old man." Something needs to be killed off as to its influence.
Knowing this, that our old man has been crucified with Him in order that the body of sin might be annulled, that we should no longer serve sin as slaves; (Rom. 6:6)
We who have died to sin, how shall we still live in it?
Or are you ignorant that all of us who have been baptized
into Christ Jesus have been baptized into His death? (Rom. 6:2b-3)
