IMO (my own thoughts/speculations)

0: Ms.Darkness is Mr.G's ELDER SISTER (a state of the universe before the stars, planets and life), his birth was likely an accident that she TOLERATED while destroying his artworks like nothing.

1: let's get something straight here right away, the so-called "God" of Supernatural-verse is more of a living concept creature filled with personality, it represents the stars and life in the cold universe (that will ultimately, inevitably end), he is not perfectly all-powerful, all-knowing, all-everywhere as the bible advertises him as such his energies are not what they used to be during the big bang event (sealing off the empty cold darkness and breathing life and energies into instead)

2: "God" on sheer principle restrained the massive shit out of himself in this episode, he wanted the hunters, witches, demons and the archangel to band together, to forge a bond of combat between eachother, to risk, grow and develop on their own, he could snap his fingers to make their life easier but he WON'T! because that's what his personality is like.

3: "Can't interfere with free will" (just like in Bruce Almighty) either again on principle and/or because he self-inflcited that flaw in his power set.

4: in the end he loved his elder sister too much to lock her up in a cage again, foolishly giving her the time necessary to recover her strength.

5: the combined mass assaults of witches, demons and angels made a painful mark on her (even then only a temporary one), a being equal to god because............she is still regrowing her former "big ban"-era strength, she's been stuck in prison for BILLIONS of years, her "muscles" are still atrophied.

refused to use the majority of it's powers because it wanted the mortal hunters, witches, demons, the archnagel to all work together, to form a bond, to grow and develop on their own.
