The descendants of Seth were called by the name of the Lord (Gen 4:25-26). 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; Rom 8:14; 1Jo 3:2). The character of Seth's descendants proves that they were the sons of God (Gen 5:3-29; Gen 6:9; Gen 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 (Gen 4:8-14), and his descendants were polygamists and murderers (Gen 4:17-23).
