The “Sons of God” are the angels. In Jude 6: it says: “And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.”
We see that God allowed sin not only to enter the world through the actions of Satan, but to be a source of temptation to the angels also. We see how all the angels became exposed to a peculiar temptation in connection with fallen mankind and we believe that Satan was involved in this temptation.
Some of the angelic host gave in to this temptation, and some remained loyal to God. So we know that all the angels of Heaven were subjected to a great test of their obedience to their Creator. All those angels who are in harmony with God, according to the Bible, have stood their test. These, we understand the Scriptures to teach, have been granted the reward of everlasting life, because they proved faithful and obedient and demonstrated their loyalty. Those who fell were bound in chains of darkness unto the Judgment of the Great Day.
