That is not Bible doctrine and is blasphemous.
The doctrine of the Word teaches that Adam was made male and female [Genesis 5:2], to multiply the living seed created in the loins of the firstborn Adam male, in the womb of the female Adam, as sons of God of the human being kind [Malachi 2:15]; and that the male and female are one spirit [Malachi 2:15], and all Adam is the same one spirit, and one bone, one flesh, and one blood. Each soul come to fruit in Adam is covered by the Atonement until they willfully choose evil after coming to the age of understanding good and evil. No one born in Adam will be a reject in the Lake of Fire for the sin of the first father of our race because the Atonement works back to the fall and fzrward to every seed born in Adam, to cover the unclean defiling deed of Adam in the fall. Not one single soul come to fruit in the Adam race of human beings is condemned at birth, but at birth is covered by the promise of the Seed of the Woman given in the presence of all the seed in the loins of Adam at the time of the fall.
No demon can be redeemed, and by your accusation of everyone being born of the evil spirit who is in fact born in the Adam spirit, you are claiming that all souls are nephillim =demons, and so not of the first father of the human race, Adam, since the fall. But you are deceived and deceiving and your doctrine is not the doctrine of the Word of God.
Every single soul born in Adam belongs to the LORD [all souls are mine, says YHWH], and was written in the Book of Life from before the foundation of the world to come forth in their season, pre-ordained, in the Adam being, as sons of God of the human being kind; and not one single soul written in that book is condemned when born in Adam, but has the Light Christ, lighting them until they come to the age of accountability, and either seek that Light and be led to know Christ, or reject that Light, and be rejects, themselves, then, in the end, and their name will be blotted out of the book of Life when they become reprobates, with no remedy.
No one, absolutely no one, is born in Adam as a reprobate, but has to choose the Light that lights them [Christ], on coming into the world, or reject that light when they come to the understanding of good and evil, and choose evil, and continue choosing evil with knowledge, until they are without remedy and get their name blotted out of the Book if Life.
Every single Adam being soul -all the seed of Adam born in the Adam spirit- is covered by the blood of the Atonement at birth, so that they can be led to know Christ by the Light that lights them at birth, until they reject that Light and get their name blotted out of the Book of Life.
If they die before coming to the understanding of right and wrong and the freewill making of their choice, then they are covered by that blood of Atonement, for it was promised to all the seed in the loins of Adam, at the time of the fall.
If a fallen angel gets seed by marrying a female Adam person, as they did do, then that seed is an evil spirit, not an Adam spirit, and cannot be redeemed and was not written in the Book of Life to come into the Adam being. The evil spirits who were begot by angels taking daughters of Adam are not human beings. They are nephillim, and there is no redemption for them.
