Another great post from Christian Apologetics UK. This thing is so full of arguments, it’s hard to choose what to excerpt!
I’ll choose something from Section 2:
Third, there is the free-will defence. Love is only genuine when it is not coerced. True love requires the ability to exercise free will. Thus, to facilitate the ability of free creatures to genuinely love God requires that one take the risk that these free creatures will choose to reject God or to violate His commandments.
Fourth, as suggested by proponents of Molinism, it is possible that only a world which was suffused with a certain amount of evil and suffering would result in the maximum number of people freely coming to know God. The doctrine of divine middle knowledge attests that God has knowledge of counterfactuals: That is, God has knowledge of what His free creatures would do under any circumstances. If this is the case, then it is possible that God has chosen to actualise a world — out of an array of possible worlds — in which the maximum number of people would choose to know God as their Creator and Saviour, without being in violation of their rights of autonomy and existential freedom of the will.
Fifth, God often uses evil and suffering to accomplish his ends. One classic example of this is in the story of Joseph being sold into slavery by his jealous brothers, an incident which set in motion a chain of events which ultimately led to Joseph being falsely accused of a crime and subsequently being thrown into prison. Later, Joseph is promoted to the position of Pharaoh’s right-hand man, and is in a unique position to be able to administer food during times of severe famine: Including the saving of his family. In Genesis 50:20, Joseph says, “You intended to harm me, but God intended it for good to accomplish what is now being done, the saving of many lives.”
Everybody needs to know how to answer this objection, so read the post.
Here’s an excellent lecture on the problems of evil and suffering by Doug Geivett, if you want something to listen to. And here’s a good text post on the problem of proving that God doesn’t have a morally sufficient reason to permit suffering.
