The image , IMO, is primarily about the divine nature...
For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.
In the beginning was the Word(logos- expressed thought)- Jesus came out of the Father, to reveal the Father, by BEING WHO HE IS. YHWH says I AM THAT I AM, Jesus says before Abraham was I AM.
...in these last days(YHWH) has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world. And He is the radiance of His glory and the exact representation of His nature, and upholds all things by the word of His power.
If you have seen me you have seen the Father, I and my Father are one...
Jesus is the image of God and we are being conformed to His image
For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren;
But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as from the Lord, the Spirit.
This is primarily about BEING. Our being is what was created in His likeness, was subjected to futility, and is now being "made new",
Col 3:10 and have put on the new self who is being renewed to a true knowledge according to the image of the One who created him--
The one new man is being made new, recreated, restored in the image of the being/nature of the one through whom YHWH created everyone who comes into the world.
Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord; seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence. For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of the divine nature, having escaped the corruption that is in the world by lust.
The true knowledge is always about "being"- IMO their is nothing more consistent in Jesus' teaching than that.
