Sons of God - Condensed Biblical Encyclopedia

The descendants of Seth were called by the name of the Lord ( Genesis 4:25 Genesis 4:26 ). This is not true in reference to the descendants of Cain. The servants of God in all ages have been called the sons of God ( Job 1:6 ; Romans 8:14 ; 1 John 3:2 ). The character of Seth's descendants proves that they were the sons of God ( Genesis 5:3-29 ; Genesis 6:9 ; Genesis 7:1 ). The character of Cain's descendants proves that they were not the sons of God, for Cain himself was a murderer, a fugitive, and vagabond ( Genesis 4:8-14 ), and his descendants were polygamists and murderers ( Genesis 4:17-23 ).
