If I set my gas hot water heater to its lowest setting and shut off the main water supply to my home will it hurt the water heater.

No, if no water is drained from the tank, by, for example, turning on the hot water in the house, a hot water leak/drip from a pipe, or opening the drain valve to the hot water heater.
