Generally we assume that God is omnipotent, and could have created the world in a single day\act, so He must have had a reason to organize creation into 7 days. Why?

In other words:

  1. Why didn't God create the world in one big act of creation?
  2. Why did God choose to create the world in 7 days, as opposed to any other number? (Probably related to this question.)

This question has an open bounty worth +50 reputation from Menachem ending in 6 days.

This question has not received enough attention.

I'm looking for explanations why G-d created the world in 7 different days. G-d created the world with 10 different utterances, so we see that G-d did make more than one act of creation per day (although it can be argued that the doubled-up utterances are thematically linked). G-d could just as easily have made all 10 utterances on a single day, why space it out over 7 days? The 50 reputation bounty is just to get attention to this question. If I like the answer I'll award more.

I assume there are midrashim and mefarshim that answer this question. – Shmuel May 19 '13 at 3:00
re "I assume there are midrashim and mefarshim that answer this question": That is neither a prerequisite for asking a question here nor a reason that a question should be an acceptable one. – Double AA May 19 '13 at 4:46

Nice +1 This is much better than your original post and is more likely to attract the answer you are looking for. – Double AA May 19 '13 at 6:18
@Menachem - OK, good start. – Shmuel May 19 '13 at 6:39

there are many answers as to why not in one saying. here's one possible answer: "By ten divine sayings the world was created. Could it not have been created by one? What does this teach us? In order to emphasize the guilt of the wicked who destroy the world that was created with ten sayings and the merit of the righteous who preserve the world that was created with ten sayings." avos ch.5 (i.e. to give the righteous more reward since they are sustaining a world created with more "work")

The ten divine sayings correspond to the ten sefirot in kabala.

As for why specifically seven days, see this: http://www.dafyomi.co.il/parsha/breisht3.htm

Wouldn't those statements be stronger if the world were created with, say, 100 sayings? – Double AA May 19 '13 at 8:26
the second part of the answer provides the reason why 6 days – ray May 19 '13 at 10:02
This does not really address the question. The world could have been created with many many sayings. In one day. – mevaqesh 12 hours ago

The world was created in 7 days because that makes it the kind of world that fits man who is nivra be'tzelem.

I.e. man expects a particular graduality of completion which is now the way the world works.

Therefore sheshes yamim taavod and bayom hashevii Shabbos.
