Either God wants to abolish evil, and cannot; or he can, but
does not want to, if he wants to but cannot he is impotent.If
he can but does not want to, he is wicked. If God can abolish
evil, and God really wants to do it, why is there evil in the
world.
Irenaeus' theodicy
'Suffering is good for us'
suffering is necessary for people to be
good: virtues are impossible unless
there is evil (natural or moral) to
respond to and correct.
