How you treat others is how G‑d treats you. How you forgive them is how He forgives you. How you see them is how He sees you.
When you show empathy for the plight of another human being, G‑d takes empathy in your plight.
When others slight you and you ignore the call to vengeance that burns inside, G‑d erases all memory of your failures toward Him.
When you see the image of G‑d in another human being, then the image of G‑d becomes revealed within you.
-From the wisdom of the Lubavitcher Rebbe, of righteous memory
