The most unexpected event happens towards the beginning of Parshat Lech Lecha. Avraham Avinu, having left his land and family to follow the call of Hashem, arrives in Eretz Yisrael only to be faced with a terrible famine. With few options available to him, he and Sarah move to Mitzrayim, where they pretend that she is his sister and not his wife, in order that the Egyptians not kill him to get to her.
(one should not rely on a miracle) and decided that going to Mitzrayim was the best option he had at the time.
Practically speaking, the viewpoints of both the Ramban and Rav Hirsch can positively influence our decision making and outlook.
May we all have the clarity to face our decisions and challenges with Emunah, Hishtadlut and clarity of thought.
