This is another "dualist paradoxical paradigm" :o)
All are children of God- in the time transcendent sense of the ultimate will of God, yet.....
Some are sons of disobedience
Some are children placed by the adoption into the "name of Jesus"- sons of obedience.
Jesus called the Pharisees, "sons of Cain" and told them that their father was "the adversary"- a murderer from the beginning.
This is about the mystery of iniquity and how God speaks in layers, wheels within wheels-
I kno we like it simple, but it is just not always so simple :o)
And you were dead in your trespasses and sins, in which you formerly walked according to the course of this world, according to the prince of the power of the air, of the spirit that is now working in the sons of disobedience.
Let no one deceive you with empty words, for because of these things the wrath(orge) of God comes upon the sons of disobedience.
Therefore consider the members of your earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry. For it is because of these things that the wrath of God will come upon the sons of disobedience, and in them you also once walked, when you were living in them.
"You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.
