Thanks for the mention.

Does God have anything to do with suffering? No. That is a whole topic in and of itself.

There are three kinds of suffering two of which are involuntary suffering and voluntary suffering.

Involuntary suffering involves all that we don't have control over: entropy regarding the body, illness, losses etc.

Voluntary suffering is giving up something in an effort, a campaign, or a goal to achieve a reward.

The third kind of suffering involves conscious work and intentional suffering which would take too long to explain in this response. Suffice it to say it is not masochism or self-flagellation of any kind.
