Oh, let me go cry in a corner because people have me on ignore.

I am not motivated by the need for popularity.
There is no mention of two natures in 1 John 3. Just a mention of those who are born of God and those who are not.
1 John 3:10 In 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. (no two natures here, just two different types of people)
The whole book is talking about discerning what is of God and what is of the devil and of the world. Not about two natures.
You would have the new nature as of God and the body as of the devil. That is Gnosticism.
