RE: "An unhappy, unfulfilling or difficult marriage does not call for a divorce, but for redoubled effort to craft a marriage that honors God and serves one another and others."

What exactly might a "redoubled effort to craft" such a marriage entail? What is the most helpful role of Christian family members, close friends, and the congregation (if any) where the couple has been worshipping?

RE: "Christians help those in ['painful, dying'] marriages by refusing to allow them to divorce for any reason other than the narrow concessions granted by Jesus."

I was in my twenties when my parents' marriage came apart. Neither parent asked me whether I would "allow them to divorce." For many months I deeply lamented where things were headed and at one point asked my pastor what I could do. He replied, "My experience tells me that the best thing would be for them to get into marriage counseling as soon as possible."

It is relatively easy to make doctrinaire statements opposing divorce on biblical grounds. Far more difficult is knowing how to engage divorcing and divorced friends and loved ones wisely over a period of many years, especially as unanticipated difficulties arise time and again. If Christian love means expressing opposition to a divorce that is proceeding on unbiblical grounds, how is Christian love best expressed after the divorce is finalized?
