Things can turn around suddenly and without much explanation. He who is favored today may be disfavored tomorrow, and he who is disfavored today may be favored tomorrow.
Such happened with David and Absalom,
“Now a messenger came to David, saying, ‘The hearts of the men of Israel are with Absalom’” (2 Samuel 15:13).
How could Israel turn away from David, and how could Israel turn to Absalom?
David fought for Israel. Absalom killed his own brother. Such things are difficult to explain, but they do happen, showing the fickleness of the public.
Be prepared for it, because it can happen at any time and to anyone.
