Hebrew “image” and Greek “image”
Though it is true that the Greek “eikon” is equivalent to the Hebrew “tselem” in word meaning, the “image” in Romans 8:29 is different from the “image” in Genesis 1:26, theologically and qualitatively!
Explanation:
“Image” and “Likeness” in Genesis
As extensively as I could study, this is what I understood regarding the “image” and “likeness” in Gen 1:26:
”Tselem – Image”
This is a 3-dimensional copy of the original!
How do I know it is a 3-dimensional copy?
Number 33:52 talks about “their molten images”! Now, a molten image is cast into a 3-dimensional figure. It is a statue or an idol.
”Demuth – Likeness”
This is the “content” or similitude (with characteristic details) of the original. It could be a drawing, a picture, a bas relief or even a sculpture. But the copy will have the important features of the original.
For example, the idolatrous “King Ahaz goes to meet Tiglath-Pileser
king of Asshur at Damascus, and sees the altar that is in Damascus,
and King Ahaz sends to Urijah the priest the likeness (demuth) of
the altar, and its pattern (details), according to all its work” (2
King 16:10).
This likeness could have been in the form of a drawing, a bas relief or even a clay model. But the details will be made clear.
The Difference:- An amateur can make a 3-dimensional image of Abraham Lincoln. But it may not look like (no likeness) Lincoln. It may look like somebody else! However, when a professional sculptor makes a 3-dimensional image of the same, it will look like (likeness) Abraham Lincoln! In other words, both made the same image but only the latter made the likeness (the characteristic features of Lincoln)!
So, the Scripture is clear, man is a 2 and 3-dimensional copy (in the physical world) of the Almighty God who is in the spiritual realm! The similitude or characteristic features also include God's creative intelligence, dominion, rationality etc.
So man is a physical copy of the spiritual God in shape and similitude!
This is all the more clear when we read:
“And Adam lived one hundred and thirty years and fathered a son in his
own likeness (demuth), according to his image (tselem), and
called his name Seth” (Gen 5:3).
It is obvious that “tselem” and “demuth” cannot mean one thing in Gen 1:26 and another thing in Gen 5:3!
So if Seth was as similar as Adam in shape and form (in 2 and 3 dimensions), then it is obvious that a human being is as similar as the Almighty God in shape and form (in 2 and 3 dimensions)!!
I would say if anyone wants to see how the Almighty God looks like, just look in the mirror!! (I know I am going to get down votes!)
This explains why God took great pains to save the humanity but didn’t do so in the case of the fallen angels!!
Image in Romans (or New Testament)
If we are already in the image and likeness of God, then what is the image talked about in Romans or in the New Testament in general?
The answer is rather simple:
We are now a physical image and likeness of God. But we will take on a spiritual image and likeness of God!!!
This is what Paul says:
“Behold, I speak a mystery to you: we shall not all fall asleep,
but we shall all be changed (from physical to spiritual). In a
moment, in a glance of an eye, at the last trumpet; for a trumpet will
sound, and the dead will be raised incorruptible (spiritual), and
we shall all be changed (from physical to spiritual). For this
corruptible (physical) must put on incorruption (spiritual), and this mortal (physical) must put on immortality
(spiritual)” (1 Cor 15:51-53).
“If there is a physical body, there is also a spiritual
body.” (1 Cor 15:44).
“and according as we bore the image (eikon) of the earthly
(physical), we will also bear the image (eikon) of the
heavenly (spiritual)” (verse 49).
“God is spirit” (John 4:24). “Now the Lord is the Spirit” (2 Cor
3:17).
The above Scriptures are very plain and self-explanatory. We are now a physical “image” of the spiritual God. This is what Genesis 1:26 is saying. But we will become a spiritual “image” of the spiritual God. And this is what Romans 8:29 is saying.
Jesus Christ says the same thing
Jesus, while discussing with Nicodemus, says:
“What is born of the flesh is flesh (that is, physical), and what is
born of the Spirit is spirit (that is, spiritual)” (John 3:6).
Jesus clarifies what He means by “born of the Spirit is spirit”:
“The wind blows where it wants to. You hear its sound, but you don't
know where it comes from or where it is going. That's the way it is
with everyone who is born of the Spirit” (John 3:8).
When a physical person is “changed” into a spiritual person, he will no longer be subject to matter, space, time and energy! He can become invisible to the physical world!
This is exactly what Jesus Himself demonstrated, after His resurrection, when He appeared out of nowhere to the disciples inside a “locked” room (John 20:19 and 26). Here Jesus behaved like a wind. The disciples didn’t know where Jesus came from or where He went!
This is exactly what Paul also, who was taught directly by Jesus (Gal 1:12), says:
“And I say this, brothers, that flesh and blood (physical man) is not
able to inherit the kingdom of God (spiritual), nor does corruption
inherit incorruption” (1 Cor 15:50).
Did Adam lose this physical image?
Not according to the Scripture! Even after Adam sinned and was expelled from the Garden, man is said to be in the image of God in Genesis 9:6:
“Whoever sheds man's blood, his blood shall be shed by man. For He
made man in the image of God”.
We also need to remember that though Adam sinned and was expelled, his own son Abel was “righteous” (Matt 23:35)!
Even before Adam sinned, the Scripture says that Adam was “formed out of dust from the ground” (Gen 2:7). So Gen 3:19 was a reminder of the same to Adam by God; “for you are dust and to dust you shall return”.
So, Rom 8:29 was NOT a restoration of something that Adam lost! It was an entirely brand new phenomenon brought by Jesus the Lord!!
