Genesis 5:3 - Wesley's Explanatory Notes

Seth was born in the 130th year of Adam's life, and probably the murder of Abel was not long before. Many other sons and daughters were born to Adam besides Cain and Abel before this; but no notice is taken of them, because an honourable mention must be made of his name only, in whose loins Christ and the church were. But that which is most observable here concerning Seth, is, that Adam begat him in his own likeness after his image — Adam was made in the image of God; but when he was fallen and corrupted, he begat a son in his own image, sinful and defiled, frail and mortal, and miserable like himself; not only a man like himself, consisting of body and soul; but a sinner like himself, guilty and obnoxious, degenerate and corrupt. He was conceived and born in sin, Psalms 51:5. This was Adam's own likeness, the reverse of that Divine likeness in which Adam was made; but having lost it himself he could not convey it to his seed.
