Adam was uniquely created in the “image and likeness” of God (see Gen. 1:26). But after he sinned and died spiritually (see Gen. 2:17 comment), his offspring were made in hisfallen image. Since everything reproduces “after its own kind,” all of Adam’s offspring (all mankind) are born spiritually dead—separated from God. It is because we are born spiritually dead that Jesus came to give us spiritual life (John 5:40; 10:10; 14:6; etc.). This is why Jesus said that we must be born again (John 3:3).
Genesis 5:1This is the book of the genealogy of Adam. In the day that God created man, He made him in the likeness of God. 2He created themmale and female, and blessed them and called them Mankind in the day they were created. 3And Adam lived one hundred and thirty years, and begot a son in his own likeness, after his image, and named him Seth.
