Biblical explanation
Genesis 6:2 says: "The sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose." Three major interpretations have historically been proposed: Angelic beings The godly descendants of Seth Powerful human rulers The Bible does use "sons of God" for heavenly beings in some passages, such as Job 1:6 and 2:1. However, Genesis 6 itself does not explicitly say: "These were angels." Jesus also said angels in heaven do not marry. Matthew 22:30. The passage therefore should be handled carefully rather than building an elaborate doctrine on a short and difficult text. The Bible clearly describes the "sons of God" and their union with the daughters of men, but it does not give an exhaustive explanation of their identity in Genesis 6.
Key takeaway
The great controversy reveals God's character as Christ ministers as our High Priest in the heavenly sanctuary. The dead await the resurrection, Christ's return will be visible and personal, and prophecy calls believers to faithful mission rather than date-setting or fear.
