Not Even a Finger Is Bruised by Chance
Nothing happens to a person below unless it has first been decreed above.
Rebbi Chanina teaches that a person does not bruise even his finger here below unless it has been declared about him on high. He learns it from the verse that a man's steps are established by Hashem, and asks what a person can really understand of his own way. Even the smallest scrape is part of Hashem's plan. Rebbi Chanina lived by this faith. When a woman tried to take dust from under his feet to cast a spell on him, he told her to go ahead, for "there is none besides Him." The Gemara explains that his great merit protected him. A person who knows that nothing happens by chance can face life with calm instead of fear.

The next time something small goes wrong today, a stubbed toe, a missed bus, a spilled cup, stop before you react and say quietly, "This too is from Hashem." You do not have to understand why. Practicing that sentence on small things builds the trust you will need for bigger ones, and it turns a moment of irritation into a moment of emunah (faith).
