[Cronos]

This is further emphasised in Col 1:15-17 15 [a]He is the image of the invisible God, the firstborn of all creation. 16 For [b]by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things have been created through Him and for Him. 17 He [c]is before all things, and in Him all things [d]hold together.

This comment by Paul is interesting in that he uses the term “eikon” or image of the invisible God to describe Christ.
An eikon or icon is, of course, not the thing its self but a representation of it just as we say of a picture, “That's you!” knowing full well it is not actually.

Paul often left out parenthetical statements that were understood by the listener as when he uses the word “panta” or “all” when he describes Christ as the creative agent saying, (see footnote on this verse in the NAB)

“..all things were created through him and for him”.

In 1 Cor. 15:26,27 Paul chooses to explain that his use of “all” has some exceptions so he as an aside notes them.
In Col. he doesn't explain what would obvious, that creation was “dia”, through Christ as an agent.
