Victory of Good
The ultimate and complete victory of Ahura Mazda is certain.
Despite current struggle, good's victory is assured. At the end of time, evil will be completely destroyed, not merely contained. Creation will be renewed in eternal perfection.
At the last, truth shall utterly prevail.
Assured victory provides hope and motivation for the struggle.
