Genesis 5:1-3 ESV
This is the book of the generations of Adam. When God created man, he made him in the likeness of God. Male and female he created them, and he blessed them and named them Man when they were created. When Adam had lived 130 years, he fathered a son in his own likeness, after his image, and named him Seth.
This passage reiterates that man was God’s unique creation, created in His image. This did not mean that man looked like God, but that he was a spiritual, rational, moral being like God. Just like his father, Seth was a spiritual being. However, the Scripture points out that Adam fathered a son in his own likeness, after his image.
Was Seth not created in the image of God?
Seth also bore the Imago Dei, but when Adam sinned, God’s image was marred, and his nature became bent toward evil. He passed this on to his descendants–to Cain, to Abel, to Seth, and to us. So rather than saying Seth bore the unadulterated image of God, the Bible says that he bore the distorted and depraved image of Adam.
