The fight for faith and joy is a good fight because...
The enemy of our Joy is evil
The enemy can kill, steal, and destroy, and if we are not fighinth for Joy then he will kill, steal, and destroy it and put a flase idol in the place of God.
We don’t fight with our own strength
The struggle is not carrying a burden, its letting a burden go
It does not involve self-exaltation but rather self-humbling
