Seth was a worthy character, and was to take the place of Abel in right doing. Yet he was a son of Adam, like sinful Cain, and inherited from the nature of Adam no more natural goodness than did Cain. He was born in sin, but by the grace of God, in receiving the faithful instructions of his father Adam, he honored God in doing His will. He separated himself from the corrupt descendants of Cain and labored, as Abel would have done had he lived, to turn the minds of sinful men to revere and obey God.

Enoch was a holy man. He served God with singleness of heart. He realized the corruptions of the human family and separated himself from the descendants of Cain and reproved them for their great wickedness. There were those upon the earth who acknowledged God, who feared and worshiped Him. Yet righteous Enoch was so distressed with the increasing wickedness of the ungodly, that he would not daily associate with them, fearing that he should be affected by their infidelity and that his thoughts might not ever regard God with that holy reverence which was due His exalted character. His soul was vexed as he daily witnessed their trampling upon the authority of God. He chose to be separate from them, and spent much of his time in solitude, which he devoted to reflection and prayer. He waited before God and prayed to know His will more perfectly, that he might perform it. God communed with Enoch through His angels and gave him divine instruction. He made known to him that He would not always bear with man in his rebellion—that His purpose was to destroy the sinful race by bringing a flood of waters upon the earth.
