And Adam knew his wife again, and she bore a son and called his name Seth, for she said, “God has appointed for me another offspring instead of Abel, for Cain killed him.” 26 To Seth also a son was born, and he called his name Enosh. At that time people began to call upon the name of the Lord.
The promise God made to mankind was that through their progeny, One would come who would eventually put an end to death by a swift kick to the serpent's skull. With Abel in the ground and Cain AWOL, that plan seemed to be off to a rocky start. But God provided Adam and Eve with Seth who produced offspring who called again upon the Lord. So while death seemed to quickly rule and reign after the fallout of the Garden, life by God's design passed the baton forward hoping to find the One who would rule and reign over death.
