Theodicies are a big deal. Whether you know the term "theodicy" or not, you probably know a theodicy or two if you're a Christian. It's pretty much required, as remaining a Christian without knowing a few theodicies would be intellectually difficult. Whether you yourself have struggled with doubt about God and his goodness, or whether someone you know has struggled with tragic loss and God's seeming silence, the problem of evil is an issue we must all face and attempt to answer. In fact, the problem of evil seems to me to be one of the biggest hindrances to the faith for many today. A theodicy, then, is just our attempt at providing a possible explanation for the evil we experience and see, as well as the seeming silence of God and his goodness through such evil.
Theodicies have been weighing heavily on my heart recently. It's hard not to dwell on the problem of evil when evil so apparently abounds in the violence, racism, and abuse we see throughout the world, and even more despairingly, in the church. And it's hard not to address the problem of evil daily when it seems to be on everyone else's mind, especially on the minds of those who aren't Christians. We live in a nation where so many claim to believe in God, his goodness, and the power of prayer despite mounting evidence that those things are impotent and ineffectual in the face of evil and tragedy. Thoughts and prayers are too often given without any indication of their effectual merit, as evidenced by the next tragedy which inevitably comes. Beyond the man-made tragedies which weigh on us all, there are also those tragedies which seem inexplicable. I was talking to a former Christian just the other day and he told me that he didn't want to deal with any other Christian apologetics if I couldn't answer the problem of natural evil. I can pin moral evil on free creatures, but how can I possibly explain how a good God could exist when creation is so clearly fashioned in such a way that requires pain and death (e.g. 2nd law of thermodynamics and entropy, plate tectonics and volcanoes, storms and winds/lightning/floods, bacteria and viruses, animals clearly created to prey on other animals, gravity and our fragile bodies, etc)?
