In the image of Christ means I’m cloaked in a robe of value and worth. It’s not intrinsic but comes from God. Just as C.S. Lewis believed. We’re not ontologically equal to God. Only God is intrinsically glorious.
I am the LORD; that is my name; my glory I give to no other, nor my praise to carved idols.~~ Is. 42:8
He shares His extrinsic glory but not His intrinsic Glory. Our glory is a derived glory. It’s an image and likeness. Only God is self-sufficient. We depend on Him as finite and dependent creatures. To want to exalt yourself and claim equality with God was the sin of Satan. It’s the height of arrogance. As C.S. Lewis states it’s the complete anti-God state of mind.
