Why is there so much suffering in the world when your all powerful lord can easily end it? Luckily we can ask the bible's version of the man who suffered most. Job.
I think it is important to note that the book of Job was written by at least two different authors. Everyone knows the story of god making a bet with a devil's advocate to get Job to curse god and how the satan made Job suffer all the ways he could think of to no avail. God wins the bet and gives Job all his shit back. However, the middle bit of the story was written by a different author as a kind of conversation between Job and three of his friends regarding Job's suffering (in poetic form). This story ends with Job calling god out, which doesn't go well, and subsequently leaves Job repenting for no apparent reason.
Focusing only on the question of why there is suffering, we get two reasons from Job. One is that god has a heavy gambling addiction- kicked out of every casino in heaven he is forced to make these bets with the satan, the other is...
Let's just stick with blaming it on women and their love of snakes, whaddya say christians?
I will probably be hitting a few more things about Job in the future (there is so much), but I wanted to get this out- MJ's death had me think about the charites he gave to which made me think of all the suffering and reminded me of one of my major questions of the god fallacy. In the meantime, I hope you read about the Ugarit so you can understand the fact that, the poem- the bit with Job and his buddies, never calls god YHWH (the christian god). It is called Eloahh (probably where Allah comes from), Elohiym (the council of gods of the Ugarit of which YHWH was one), or El Shaddai ( I consider to be mother nature). Of course, Wikipedia says there may be a Sumerian source that the entire story of Job was copied from, I haven't looked into that but I think it is likely (as is the case with most of the Old Testament).
