There are so very many questions and in researching fact, many things that were unclear become clearer.
“If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.”
James 1:5 KJV
Question: “Who were the sons of God and daughters of men in Genesis 6:1-4?”
Answer: Genesis 6:1-4 refers to the sons of God and the daughters of men. There have been several suggestions as to who the sons of God were and why the children they had with daughters of men grew into a race of giants (that is what the word Nephilim seems to indicate).
