Wow, I just finished watching Lee Strobel's A Case For Faith and that was his whole argument for why there is suffering in the world.
Christianity teaches us to find what is good in even the bad things we experience. Good can come even when evil is visited upon us. Remember, the most important moment in Christian history was the execution of its first leader, Jesus. For Christians, this moment of evil and suffering visited upon an innocent man led to the triumph of good over evil.
It is moving to be sure and I can see how looking for something good in the face of something evil can really help people to cope with the bad things. However, I still think that the whole documentary needed something more to answer the two questions posed by Charles Templeton.
1) Why is Christianity considered the only way to God?
2) Why would a loving God permit so much suffering in the world?
