Thanks for your comments.
I try to base my beliefs purely on the Bible, not what appears in literature.
The following Scriptures are unambiguous as to who God views as sons, as well as brothers of Christ!
(Matthew 12:50) whoever does the will of my Father who is in heaven, the same is my brother, and sister, and mother.”
(Matthew 13:38)
The field is the world; as for the fine seed, these are the sons of the kingdom;
(Matthew 25:40)
To the extent that YOU did it to one of the least of these my brothers, YOU did it to me.
(Mark 3:35)
Whoever does the will of God, this one is my brother and sister and mother.”
(Luke 8:21)
In reply he said to them: “My mother and my brothers are these who hear the word of God and do it.”
(John 1:12,13)
However, as many as did receive him , to them he gave authority
to become God’s children.........
(John 15:14)
YOU are my friends if YOU do what I am commanding YOU .
(Rom. 8:14)
For all who are led by God’s spirit, these are God’s sons.
(1 John 5:1)
Every one who believes that Jesus is the Christ is a child of God .......... (Revised Standard Version)
