Is it G*d who is fickle, or is this an allegory of the uncertainty we feel about attempting to discern G*d's will about important decisions?
The Haftorah portion, in a way, answers this question.
|ה עַמִּי, זְכָר-נָא מַה-יָּעַץ בָּלָק מֶלֶךְ מוֹאָב, וּמֶה-עָנָה אֹתוֹ, בִּלְעָם בֶּן-בְּעוֹר--מִן-הַשִּׁטִּים, עַד-הַגִּלְגָּל, לְמַעַן, דַּעַת צִדְקוֹת יְהוָה.||5 O My people, remember now what Balak king of Moab devised, and what Balaam the son of Beor answered him; from Shittim unto Gilgal, that ye may know the righteous acts of the LORD.|
Rabbi Dovid Siegel expands on this:
We now understand why Micha isolated this incident between Bilaam and the Jewish people when demonstrating Hashem's ultimate love for His people. [...] In truth, a father always remains a father during the most trying times and his love for his child is never tainted. Although he may punish his child this too is an expression of love and concern and should never be viewed in any other way. No one should ever forget that the Jewish people are Hashem's children and His boundless love and concern for them will always be there for them.
In this trying time of struggle in Israel, this may be a comforting reminder that Daddy's watching us.
This is also the source of the idea of "the remnant":
6 The remnant of Jacob shall be,In the midst of the many peoples,Like dew from the Lord,Like droplets on grass--Which do not look to any manNor place their hope in mortals.7 The remnant of Jacob
Shall be among the nations,
In the midst of the many peoples,
Like a lion among beasts of the wild,
Like a fierce lion among flocks of sheep,
Which tramples wherever it goes
And rends, with none to deliver.
8 Your hand shall prevail over your foes,
And all your enemies shall be cut down!
