Der Aibishter Baruch Hu, blybt nit kayn baal chov, far yeder guter zach vos a Yid toot, tzolt ayr bemaytav mit bunay, chayei umezonay revichay ~ R’ Yosef Yitzchak of Lubavitch zt”l

G-d does not remain in debt, for every good thing a person does,  he is recompensed grandly by G-d, with children, health and livelihood, in abundance.
