Sharp Iron and Soft Shoulders

What would a life without conflict actually look like? I have no idea. I raised five boys, all now in adulthood, but there were some moments, if you know what I mean.

Ironically, I grew up in a home that felt fairly devoid of conflict. I never saw my parents fight. My younger brother and I are very different: I played sports, and he was in Boy Scouts. I am an extrovert; he is introverted and perhaps the most mellow person I know on the planet. My house was peaceful, and I thought that was normal. In fact, I entered marriage as a young pastor believing that my marriage would look just like my parents’, and in that simple expectation, I spent many years believing I was failing.

To pursue that peaceful, conflict-free marriage, I had to become smaller. Vague opinions. Shallow honesty. Staying out of the hard conversation. Even little white lies, told just to avoid disappointing my wife. But that’s not peace, and it’s not the life God created me to live. That’s life without substance: physical, emotional, intellectual, spiritual. Two people who actually believe something will eventually collide. That’s not a flaw. That’s what it looks like when two real people are actually present with each other.

So I’ll say it plainly: I spent years treating conflict as if it were a sin. I could not have been more wrong. It’s inevitable wherever people with real convictions live in real proximity, and under the right conditions, it’s actually beneficial. “As iron sharpens iron, so one person sharpens another” (Proverbs 27:17). Iron doesn’t sharpen iron by agreeing with it. It sharpens through friction.

Ask yourself honestly: who has sharpened you? I’d bet it wasn’t the person who told you what you wanted to hear.

Here’s the picture I keep coming back to, especially now that I spend most of my week coaching pastors through exactly this. An axe brought to the grindstone deliberately is used as it was made to be used, and it comes away sharper. Swung at carelessly, that’s not sharpening. That’s destruction. Same tools, completely different outcome, depending on whether the conflict is submitted to a purpose or just released as force. That’s the difference between conflict and cruelty. Not whether sparks fly, but whether something is actually being shaped.

But that picture needs a caution, or it gets misused. A grindstone isn’t a posture you get to wear into every relationship. It’s a tool you sometimes carry, not an identity you adopt. Treat everyone you love as raw iron that needs sharpening, and you won’t sharpen anyone. You’ll just wear them down until they no longer want to be near you. The grindstone has a time and place, and so does the soft shoulder. Knowing a person well and knowing what they most need in a given moment is part of loving someone well. And that only comes from actually paying attention.

Scripture doesn’t tiptoe around this either. Paul confronts Peter to his face over how Peter was treating Gentile believers (Galatians 2:11–14). That’s public disagreement between two apostles, and the choice they made in that moment either produced kingdom benefit or brokenness. Scripture doesn’t pretend it was easy, and neither should we.

Without conflict, where would your light actually shine? A good attitude is easy when everyone agrees with you. That’s not light. Nobody notices a candle in a room that’s already lit (Matthew 5:13–16). Jesus goes further still. “Eye for eye” was a defensible ethic, and he takes it and says love your enemy instead (Matthew 5:38–48), then asks the question that still stings: If you only love the people who love you back, what reward is there in that?

It’s the same discernment the grindstone requires: knowing someone well enough to bring what they actually need, even when that isn’t what you’d prefer to give. Sometimes love looks like the soft shoulder. Sometimes, in a coaching conversation or in my own marriage, it looks like the grindstone.

Here’s what I keep coming back to, both for myself and for the pastors I sit across from. We were in sharp conflict with God. Not tension. Real, deserved conflict. And Paul tells us exactly how God responded to it: “God was reconciling the world to Himself in Christ, not counting people’s sins against them.” (2 Corinthians 5:17–21). We tend to stop right there, grateful and relieved for what He has done for us. But Paul doesn’t stop there. He goes on to tell us that God has given us the ministry of reconciliation. We are His real-time representatives, His ambassadors.

That’s not just a metaphor. It’s a job description, and it’s the one I try to live inside every time I walk into a conflict, whether it’s in my own home, in a social media post, or in a church I’ve been asked to help. Grace-giving. Open. Thoughtful. Wisdom-seeking. Curious. Honest about anger without being ruled by it. At all times, in every conflict, our calling is to represent the heart of God. Period.

This is where the grindstone actually belongs. Not as its own calling, but as one tool in an ambassador’s hand, alongside the soft shoulder. An ambassador doesn’t walk into a room to sharpen. An ambassador walks in to represent. Some days that means the friction of iron on iron. Most days, if I’m honest, it means the soft shoulder.

But the tool is never the assignment. The assignment is always to represent Him well.

Paul and Barnabas show what that looks like when two ambassadors read the same room differently. Paul reached for the grindstone. Barnabas reached for the soft shoulder. For a while, that difference cost them everything: they went their separate ways over it (Acts 15:36–41). I know what that costs, because I’ve watched pastors and churches pay it. But it didn’t stay that way. Years later, Paul writes that Mark has become useful to him again in ministry (2 Timothy 4:11), useful in part because Barnabas hadn’t given up on him when Paul had. Whatever tore in that first conflict got worked all the way through.

That’s the whole aim, really; not to become a permanent grindstone, and not to become only a soft shoulder either. To read the room in front of me and represent Him well, I have to know which tools to choose.
