And God said, “Let us make a human in our image, after our likeness; and these will rule over the fish of the sea and over the bird in the heavens, and over the beast, and over all the earth, and over every creeping animal that creeps on the earth.” — Genesis 1:26
As far as an image is concerned, it is not the likeness of another thing but is after a likeness of it, which explains the wording “Let us make a human in our image, after our likeness.” A person with a spiritual character is an image, but a person with a heavenly character is a likeness or exact copy.
Genesis 1 deals with the spiritual person, Genesis 2 with the heavenly person.
The Lord calls the person of spiritual character (or an “image”) a child of light, as he does in John:
Those who walk in the dark do not know where they are heading. As long as you have the light, believe in the light, in order to be children of light. (John 12:35, 36)
He also calls such a person a friend:
You are my friends if you do whatever I command you. (John 15:14, 15)
But the person of heavenly character (or a “likeness”) he calls God’s child in John:
As many as did accept him, to them he gave the power to be God’s children, to those believing in his name, who had their birth not from blood or from the flesh’s will or from a man’s will but from God. (John 1:12, 13)
