In the precious chapter, it was recorded that Adam and Eve gave birth to Cain and Abel, but was corrupted by the ugly incident where cain killed Abel.
So in this chapter, the story would have been...
and Adam gave birth to Cain, and then Abel but Cain killed Abel...
But instead this chapter said
and Adam beget Seth
So this means
When we give our lives to God, our past doesn't exist, He wipes it clean like you never did anything wrong before.
God help us
