Who are the 'sons of God' in Genesis 6:1–4? This question has intrigued many commentators throughout church history. Were they fallen angels? Mighty rulers and noblemen? According to the Biblical data, they were most likely a dwindling godly lineage of men from Adam to Noah who sinned against God by marrying whosoever they chose, regardless of whether they were in the faith or not. Noah was the last of this lineage, saved from the Flood. Important applications of this view are also discussed.
