For two Christians, there is no such thing as irreconcilable differences. If two people believe the Gospel, then for the one who sinned, the Gospel compels them to repent and ask forgiveness. For the one sinned against, the Gospel compels them to forgive their offender.
One of the hardest issues to address in the Christian life is the issue of suffering. Countless words have been devoted to the topic, but no matter how much is said, it never seems that the right words are found. There are too many kinds of pain, too many types of suffering, and too much sorrow in the world that is unable to be explained or comforted by any one book, sermon, or blog post.
