Here is the source from
Rav Chaim Paltiel
Rav Chaim Paltiel (Peirushei HaTorah LeRav Chaim Paltiel, Bereishis 2:3) explains the pasuk and its switch of tense in a way that dovetails with our discussion. Hashem wants man to be a partner in the creative process, to be devoted to recreating himself into an improved and better person. The Torah writes that Hashem stopped doing all His work “asher bara,” that He had created, in order for us to be the ones “laasos,” to do and continue where He left off, making us, in a real sense, partners in creation.
