One Gesture

Sometimes, a man whose deeds are corrupt will live to be 70 years old because of one word he uttered or one gesture he made in complete sincerity, entirely for the sake of Hashem. It was essential that he be born for this single solitary word or gesture. It could not have been done by anyone else, for no two people were created exactly alike since the beginning of the world until the end of days.

(Rebbe Pinchas of Koretz)
