This passage gives us the basis of human dignity. Man is the image bearer of the Creator, made in His likeness. Though this image and likeness have been marred through Adamic sin, yet they are still man's dignity. God's people must always oppose illegitimate killing on this ground. Murder, abortion, euthanasia are all blasphemy.
Man is an empire builder by creation.
The image of God in man is his regal character and drive, which mirrors the regency of the Creator. Even after the fall man is an empire builder, whether in business, politics, the arts, the sciences, or the church. He is constantly trying to increase his sphere of influence. This is good because God made man in this way. It only becomes warped and perverted into lawless aggression through the fall.
