There is no reward in this world for mitzvos ~ Kiddushin 39b

Blessings are not payments for our mitzvos but rather, they are benefits that help us to serve G-d at a higher level.

When we enjoy a nice meal or a moment of nachas from our children, or we close a good deal or take a relaxing vacation, G-d is not paying us for our efforts. Rather, He is saying, “Rest up and continue to serve Me.”
