God sent His word to become tiniest flesh and grow from that tiny state to become Lord and fill the universe. That is kind of what Kuriou means. Etymology of Greek for Lord implies growth from tiny to big and overflowing. The Greek word "Kyrios" (κύριος) has its etymological roots in the Proto-Hellenic *kúrios, which derives from the Proto-Indo-European (PIE) root *ḱewh₁-. This PIE root *ḱewh₁- carries meanings related to "swelling," "spreading out," or "being strong" and "prevailing." It means he starts being hardly lord at all, then becomes lord by overcoming, growing, spreading in influence. ChatGPT puts it like this “The word "Kyrios" (κύριος) in this sense could metaphorically describe someone who wasn't always a powerful lord but gradually became one by prevailing and growing in influence, much like something that starts small and swells or spreads out over time.”
Believers can be part of his lordship growth and also have their own similar growth by overcoming. This leads to thrones and crowns.
