Get your teaching from scripture only, because of demons who teach men the doctrines of demons. And many of those men taught thereof believe it.
Here is who has the right to be called children of God, anyone else does not have that right, as they are not.
John 1
10 He was in the world, and the world was made through Him, and the world did not know Him. 11 He came to His [
c]own, and His [
d]own did not receive Him. 12 But as many as received Him, to them He gave the [
e]right to become children of God, to those who believe in His name: 13 who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
And there are many other supporting words of God to the same effect.
1 John 3:1
Behold what manner of love the Father has bestowed on us, that we should be called children of God! Therefore the world does not know us, because it did not know Him.
