The Midrash (Bamidbar Rabbah 10:1) explains that the word ויכולו signifies Hashem's longing to create the world. During the weekdays, the primary objective is to ensure that all actions are for the sake of Heaven, not to get attached to physical actions, but to long to transition to the aspect of Shabbos. This longing awakens Hashem's desire towards us.This desire culminates on Shabbos, as the Midrash explains from ויכולו that Hashem longed for creation. Through this longing, we attain chochma and binah, aspects of Shabbos, and da’as, which applies to the weekdays. This is symbolized by the “sockets of gold” on which the six days of the week are established, and it is reflected in the three Shabbos meals that sustain everything.The Chidushei Harim also explains the pasuk “on the sixth day they will prepare” (Shemos 16:5) to mean that rejoicing in anticipation of Shabbos is the preparation that awakens the light of Shabbos.

"May God show you favor." The Midrash asks (Bamidbar_Rabbah.11.7): but doesn't the Torah elsewhere say Hashem does not play favorites, אשר לא ישא פנים ולא יקח שוחד? Answer: this verse applies when we do God's will, and this verse applies when we don't. Sfas Emes asks: but when we're doing God's will, why would we even need favoritism? Answer: it means may God count a little as if it were a lot. (A Midrash (Midrash_Tanchuma%2C_Nasso.10) also says, in connection with our verse, that Hashem says, "My people show extra favor to Me! I said to recite a blessing when they eat to satisfaction, but they recite a blessing even on an olive-size morsel of food." So you see this is what it means to show extra favor: rejoicing in the tiniest opportunity and counting it as significant.) And it depends on how the person sees it. If a person rejoices at being able to do God's will even in a small way, then God too finds that mitzvah immensely precious. This rejoicing is an expression of the person's innermost essence. And this is what it means וישם לך שלום. Shleimus, completeness, is that innermost point of truth, whose radiance, even the tiniest ray, contains its everything. God is called Shalom; that means God is the completeness of all that exists. When our focus is God's will, that means we're focusing on that innermost point of a mitzvah which is its everything. It's shleimus. The size of a mitzvah is irrelevant when you focus on this essence, on doing God's will.
