Every time a person does a mitzva, it’s a kiddush hashem. Anything that makes the name of Hashem holy is considered a Kiddush hashem. When somene shows the rabim even if it’s only jews that he has mesuras nefesh for a mitzva, it’s a kiddush hashem. When the nations see that Hashems’s chosen people to good things it’s a kiddush hashem.
