Your essay strayed a bit when I started to read it and got very complicated - more than necessary. Jesus was called the Son of Man, the Son of David, and the Son of God. His family tree was enumerated. The Bible also calls Adam the first Son of God. Therefore, the lineage of Adam and Eve were called the Children of God, the Sons of God, whereas the lineage of Mankind were called the Sons of Men.

Read properly the Bible is not confusing..
