Motivational interviewing is quite helpful for this purpose. Not only that, but even reasonable people struggle with “flesh” and “ego” and IME, most people do not take very well to being “corrected.” There are some wise people who do, and they are the ones who would go seeking it on their own. So there are a lot of factors contributing to whether they should. You were likely successful in using scripture to correct someone because you were a pastor and they expected it coming from you. Additionally, people likely went to you voluntarily, specifically for that purpose.
In some cases this is true. A couple came to me or a feuding family, and expected correction from a pastor.
But in most cases where I corrected or appealed using Scriptures the person had no idea I was going to even be there before that. I showed up at their door, invited myself in, made an appeal as best I could presenting the Scriptures, and reiterating that we care for them. Quite a few repented.
Old fashioned? Maybe. But so is Paul's advice:
2Ti 3:16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness,
2Ti 3:17 that the man of God may be complete, equipped for every good work.
If that sounds like in your face behavior, sometimes it was. What else was there to lose? Sometimes the people had left their family and were in danger of rejecting God altogether. At that point a rebuke that presents the situation for what it is may be the only thing that will wake them up.
There were also a few who did not repent. I tried everything I could to make them understand we loved them, wanted them to reconsider, and that ultimately they could choose what they wanted. I wasn't there to make their choice. But I was definitely there to present the choice to them in a way that clearly showed it was a spiritual decision that would impact their whole life, for good or evil. Some situation really are that and demand no less.
And I have seen it work from non-pastors as well.
I don't suggest this for just any little issue however, and I don't think there is anything wrong with some of the methods you describe, especially in situations where it hasn't gotten to a last ditch effort to save the marriage and the soul of someone who is rejecting God's ways.
And from a personal perspective it is completely uncomfortable. I didn't like those situations at all. However, I still think it was the right thing to do.
That is not to say we don’t use scripture in our sessions. We just don’t correct people with it. Instead, when we talk about their values, some of our important questions are “how does God fit into your value system?” and “If I were to ask God what your values are, what would he tell me? Would he tell me they are his values?” Just because we don’t “correct” people, doesn’t mean we don’t use scripture to challenge them or shed light on a situation.
I think that is fine. And in most cases there is no reason for direct confrontation. However, when you say "challenge" vs. correct, it may be terminology differences as well. You can allow someone to think it through themselves and it is still correction.
Our challenges are gentle; they are not “rebuke” or “correction.” There is a way to do it that makes it seem like the idea came from them, not from us. In that way, it becomes far more meaningful to the client. We are not in a position of “expertise” or “authority.” They are the expert in their own life, so we do not walk into a coach/client relationship with more knowledge or trying to “teach” them anything.
I think that is often appropriate. However, Jesus was not always gentle in rebuke. Paul was not either. And he told Timothy to not be always either.
I do recognize that you have a very good mind for recognizing the details in each relationship and situation, so I do not doubt you know how far to go in the various cases.
I just think that there are times when full out rebuke is still appropriate. Fortunately we don't see them often.
If someone is in sin, rather than point that out to them, we ask questions that lead the client to discover for themselves how it is sin, and what the consequences of their sin is on the people they love. Then we work together to figure out how they would like to address it. But…chances are, there are going to be a lot of “sins” that each person in the couple is going to need to work out. It would be terribly unwise to sit there and point it out because their experience of that would be condemnation.
We also consider the purpose of the relationship. We coach people. That is, we help people figure out how to fill in the gaps in their lives, particularly their gaps between what they say their values are and what their behaviour says their values are. If people value the Bible, but they are not living it, then it’s something we address with them because that is what they are seeking. But if someone is there for a transition from one profession to another or to take a relationship to a next step, etc, then there is absolutely no place for “rebuke.”
I don't think we are too far apart really. I do think though there are times for full rebuke, and many times for "challenging".
