The answer to this question is found in two passages of the NT:
- Heb 1 discusses that Jesus was MUCH greater than the angels
- Heb 2:6, 7 - ... What is man that You are mindful of him, or the son of man that You care for him? You made him a little lower than the angels; You crowned him with glory and honor ...
Thus, the humiliation of Jesus would have been still significant if He had descended to the level of a mighty angel; but Jesus' humiliation was to the lower level of humans according to Phil 2:5-8.
However, Jesus' humiliation was even greater than just becoming a human - He also became subject to death, even the very ignominious death on a cross!!
The "glorification" (a word not used in Gen 1) of humans in Gen 1 is a simple statement of the nobility of humans as humans and their ability to procreate by "being fruitful and multiplying". Actually, the image of God in humans is clearly stated as follows:
- the ability to procreate
- the (delegated) authority to rule earth and its creatures (as deputies of God)
Now, while these delegated abilities in the image of God were granted as creation, they are only small shadows of the much greater abilities of God who created them. Thus, humans have some of the image of God but are certainly not equal with God.
By contrast, Jesus, according to Phil 2:9-11 was much greater after his incarnation:
Therefore God exalted Him to the highest place and gave Him the name
above all names, that at the name of Jesus every knee should bow, in
heaven and on earth and under the earth, and every tongue confess that
Jesus Christ is Lord, to the glory of God the Father.
That is, Jesus was restored to His former place of honor just as He requested in John 17:5 -
And now, Father, glorify Me in Your presence with the glory I had with
You before the world existed.
John summarizes this when he says about Jesus vs humans:
John 3:31 - The One who comes from above is above all. The one who is
from the earth belongs to the earth and speaks as one from the earth.
The One who comes from heaven is above all.
