I fully accept the following citation as an expression of my own thinking.
"However, when one enters the Christian view of reality fully, it is clear that Christian theology has a doctrine of evil—both of its origins in the Fall and of its continuing presence due to sin. Christianity takes evil seriously, and reveals the character and goodness of God in contrast to the evil that grieves him. The Bible also teaches that God has morally sufficient reasons for evil’s present existence, and that he will judge all evil and remove it in the end. Christians are not in a position of being able to claim that they know the purpose behind any and every particular instance of evil, or that the relationship between evil and God’s loving designs is entirely without mystery. Lest we become like Job’s “friends,” we must avoid simplistic explanations or quick justifications for someone’s suffering; rather, we direct them toward to the character of God, who can be trusted, and the truth that he has revealed."
