Do we know the spiritual condition of Job's sons? Maybe they were believers and he'd see them again in heaven. And animals are animals. They reproduce and can be replaced.
That which we're 'observing' is that even in the loss he experienced, he didn't get mad at God. Didn't he say something to the effect that 'God gives and God takes away, blessed be the name of the Lord'? And in the end, didn't he and his wife go on to have more kids and regained the lost livestock. We and those around him didn't see him getting mad at / blaming God for his losses. His wife, on the other hand, wanted him to 'lay down and die' didn't she.
Satan isn't really a psychopathic moron -- far from it. He's a liar ,though. He knows that his eternal destination is in hell and it won't be pretty for him. And he wants all the company possible. He wants people to think that once all of us dull, boring Christians are Gone that the 'rest of the world' is going to have a big party. No negative affects of all that 'fun'. And when 'they' find out the Real Truth -- he will laugh at them -- in the midst of his own pain and eternal suffering. The utter darkness of his world without God.
Satan has been doing everything possible to thwart God's plan for mankind and this world. From evolution to same-sex relationships and marriage and abortion.
@Dovegiven -- you'd brought up the horrible things that are happening to kids on the way up to this country. That God should be stopping all of that. Why does God permit horrible things to happen to innocent children. Well -- the holocost Also happened. There are those who wanted to pretend that That never happened to the Jews by the Germans. There Were a lot of people who Did survive. We have a hard time realizing that human beings can really act That way to fellow human beings. We are capable of treating others even worse than animals.
Maybe God is letting us observe that people Can and Do help each other in times of great distress. That the human spirit Can withstand a Lot.
God's original plan was to give Adam and Eve one 'law' to follow. There was a beautiful garden all set for them to enjoy and propogate. Everything was for them, except for the tree of the knowledge of both good and evil. Then that serpent got in the picture. Were they going to obey God's Word or fall prey to satan. Well -- as they say -- the rest is 'history'.
With the knowledge of Good Comes Evil. People have the capacity of doing great, wonderful things for each other and then again -- doing great horrific things to each other.
But -- eternity Is in everyone's future. Believers have the New Jerusalem to look forward to.
