[My apologies this would have been better posted in Christian Scriptures forum]
I have come across a few different views on this, at least they seem to me to differ somewhat, and not sure who is right, perhaps they all hold some truth?
I am speaking of course of Genesis 1:26,27
Then God said "Let us make man in Our Image, after our likeness..."
1. Some take it in the sense of man is just an image of God.
2. Other point out that the verse says "in Our Image", and say man is not the Image of God per se, but made in the Image, the Image being Christ Himself, God the Son (2 Corinthians 4:4; Colossians 1:15). Man and the Divine Image are therefore not identical.
3. Yet others see distinction of meaning or nuance between the nouns "image" and "likeness" - image for them refers to the natural or physical aspect, and likeness to the spiritual or ethical aspect of man's constitution.
However if verse 26 is taken as announcing the decision of God to create man "Let us make man..." and verse 27 the fulfilment of that decision "So God created man in His own image, in the image of God created he him..." there is no mention of likeness in verse 27, which suggest verse 26 has but one notion to convey, not two.
It seems to me the first view sees no special reference to Christ in the term Image.
I must admit until I came across Phillip Edgecumbe Hughes book The True Image, I took the sense of it to be no. 1.
What way do you understand this verse?
We know that God is Triune, in 3 Persons.
So, to make man in "our" own image means that man was created trichotomous. Man has a material body, and an immaterial soul and spirit. Paul differentiated between soul (mind) and spirit in 1 Cor 14:15.
Hebrews 4:12 also differentiates between sould and spirit.
What did God say about eating of the forbidden fruit? In the day you eat it, you shall surely die. The original Hebrew says "dying, you shall die". Did Adam fall dead on that day? No. But his relationship with the Lord ceased. He became spiritually dead to God, unable to approach Him. So what actually died on that day was Adam's human spirit. But Adam's physical body continued to live, but now, it began to die physically over time. That's what the Hebrew "dying" refers to.
So, when Adam ate the fruit, he immediately died spiritually, and began to die physically.
So, because of this, all humans are born physically alive but spiritually dead (Rom 5). At the moment of faith in Christ, the person is born again, or regenerated, becomes a new creation. So, unregenerate man is dichotomous; body and soul. Regenerate man, otoh, is trichotomous; body, soul and spirit.
Recall what Jesus told the Samaritan woman at the well in John 4:24 - God is Spirit, and his worshipers must worship in the spirit and in truth.”
In the website, Bible Hub.com, only 2 out of 28 translations capitalize the second "spirit". What Jesus was telling the woman was, in order to worship God, one must possess a human spirit (a live one). Therefore, unregenerate people cannot properly worship God.
To summarize, humans are born dichotomous, and at the new birth, or spiritual birth, become trichotomous.
So to be "in the image of God", man must become born again.
