It is balanced by radiation pressure, and gas pressure.
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.
In the case of a star (that is not actually going nova or supernova) they are balanced.
The force of gravity. This is the only significant inner force in any star.
There is no force opposite to gravity (except in a star where the light pressure from the fusion in the core holds the star up against gravity).
Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.

Gravity is the force that causes stars to be created

"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."
