Christians alone are in a position to rescue the perishing. We dare not settle down to try to live as if things were 'normal.' Nothing is normal while sin and lust and death roam the world, pouncing upon one and another till the whole population has been destroyed.
Lust and self-mutilation are closely related impulses. There are also self-mutilators among knowers: they do not want to be creators under any circumstances.
It is not lust alone that one should be afraid of in the life of the world. There is also anger. Anger arises when obstacles are placed in the way of desire.
