If we're going to accept this logic wouldn't it come next that death and earthly suffering are also punishments?
Call me a brainlet, but my addled Catholic-drifting-Orthodox brain understands death to be the point at which you put your pencil down and hand in your paper; if you've lived as a Christian should you should have no dread of death. Suffering and hardships are part of our fallen world; Adam and Eve's sin let death and dying into the world and we've been feeling the repercussions ever since. Apart from that, the earthly consequences of sin lead to pain for the sinner and those around him, don't they? So, why are we looking at God as the culprit at all?
If I'm wrong here, please, set me straight.
