Poiēma is built on the verb poieō, to make. It is the noun: that which is made, a thing crafted, a workmanship. The same root gives English the word "poem." A poem is a poiēma, a thing composed and shaped by an author for a specific reason. Sha'ul knows what he is doing when he picks this word in Ephesians 2:10: "for we are His workmanship (poiēma), created in Messiah Yeshua for good works." The word is doing two jobs at once. It is naming you as an object made by an Artisan, and it is naming you as a composition shaped with intent.

The only other place Sha'ul uses poiēma in his letters is Romans 1:20, where it describes the visible creation, the things that have been made by HaShem so that His invisible attributes can be seen through them. Same word, same Maker. Sha'ul is saying you and the creation belong to the same workshop. You are not a generic outcome. You are not a random arrangement that happened. You are a poiēma of the same hands that made the stars and named them. That is the Hebraic ma'aseh translated into Greek without losing its weight. Each English translation that renders poiēma as "workmanship" preserves the meaning. Most readers still read past it because they do not know that the word holds the root of "poem." Once they know, the verse changes. You are not just a thing made. You are a composition. There are stanzas of you the Author is still writing.
