I'm not sure I understand what this means, neither in English nor my native language. "In his image", as I interpret it, means that God intends to create an entity identical in looks and powers to himself.
But that can't be it. Well, I have no idea in terms of the looks, but I certainly don't have God's powers. If so, I would, too, be able to create an identical copy of myself, and an entire world myself, and do all kinds of other supernatural things, which I sadly don't. So, what does the phrase mean? "In his image"?
I've heard this all my life but only recently started really wondering what these fundamental Bible words mean. I find the very beginning of the Bible to be by far the most interesting.
