image
"in his image"
god is a spirit, and hence 'his image' means that God's spirit was in man.
man lost it due to sin. christ came to restore man to that former state. and hence he died (penalty for sin) shed his blood (cleansing) and put his holy spirit within us (baptism of the holy spirit) in the book of acts.
only those who have received this are spiritually restored to the original state.
