If you track "sons of God" through the Bible, you'll see this refers to those came directly from God, Adam, Angels, and Christians, and, of course, the Only Begotten Son, Jesus, though He is unique of course.sons of God means men of a certain bloodline that would branch off and be uncorrupted to bring forth Jesus from (the Branch and Shoot the prophets spoke of, how about that! The branching off, a branch from a family tree, the branch of the bloodline)
Much love!
