In Hebraica it is customary to name a book by its first word. The first word of Genesis is used again by Jacob. He used that same word to describe his firstborn son. Hint, hint. The book is about God's only begotten. We can become sons of God, but not begotten at birth like Jesus. "I believe in God, the father almighty and in Jesus Christ his only son,conceived of theHoly Spirit...." did I say that right? Anyway, not anything was made that was not made by him.
