Matt was on the London Underground, halfway up one of those very long escalators, when he saw an elderly man who looked like he was having a heart attack. The colour had drained from his face. He was clammy, gulping for air. His wife was clearly frightened. Matt clocked all of it in about half a second.

And then he kept walking. Straight past.

The escalator was barely moving because an elderly couple ahead were hauling a mountain of suitcases up a step at a time. A queue had built behind them, people moaning at the delay, then barging past and climbing over the luggage. Everyone was doing it, so everyone did it. By the time Matt reached the top, the couple were off to the side, and a whole river of people just kept walking. Him included.

And Matt has had some medical training, too. He didn't guess what he was looking at. He knew. And he still walked past.

Why? Because everybody else was walking past.

Why a Whole Crowd Can Do Nothing

The strange thing is that Matt was, at the time, researching a case from 1960s New York. A young woman named Kitty was attacked and killed in the street while, according to the papers, a crowd heard it happen and nobody came to help. New York got branded the unfriendliest city in the world.

But the psychologists who dug into it found something different. It wasn't that New Yorkers were cruel. It's that we model our behaviour on the people around us. If nobody else steps in, you probably won't either, even when it cuts clean against everything you believe. They called it the bystander effect.

Most of the time, thankfully, it's not life and death. It's the group chat where someone forwards a meme having a dig at the very thing you believe, and you just hit the laughing emoji because it's easier. It's the Monday morning at work where everyone's swapping weekend stories and you mention everything except the one thing that actually shaped your life, because you don't want to be that person.

Same instinct. We read the room and file off the bits that don't fit. We learn it young, in the playground, colouring inside the lines like everyone else, and it follows us all the way through. Say the right things. Like the right things. Whatever you do, don't make it weird.

It's called fitting in, and we're all good at it. As Brené Brown puts it, "If I get to be me, I belong. If I have to be like you, I fit in."

What Fitting In Quietly Costs

Does it work? Up to a point, yes. Society runs on a bit of conformity. We all need to drive on the same side of the road. Fitting in feels safe. Nobody gets rejected for agreeing.

But there's a cost to doing it all the time. Think about masking, hiding how you really think or feel just to blend in. The research is sobering. The more you mask, the more anxious, disconnected and lost from yourself you tend to become.

Which is a very modern way of describing something Jesus said two thousand years ago.

"You are the salt of the earth." — Matthew 5:13 (ESV)

Salt is a brilliant image, because salt has one job — to not taste like everything else. The moment it blends in, it stops being salt. It's just powder.

Jesus puts it bluntly. "If salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet."

There's a detail in the original language that's easy to miss. The word Jesus uses for salt losing its taste is mōranthē — the root of our word "moron". He's making a pun. Salt going flat and a person going dull and flavourless are, in his words, the same thing. In Jesus' day salt was dug from around the Dead Sea, mixed with other minerals, and if you left it lying about, the salt itself could leach away. You'd be left with a little pile of white powder that looked like salt but did nothing.

It sounds harsh, but it isn't a sentence on a person. The whole story of the gospel is people getting their saltiness back. Peter denied even knowing Jesus three times, to people's faces, and Jesus restored him. So this is a warning about a direction, not a verdict. Keep dialling yourself down to fit in, and one day there's nothing left to taste.

You're Not Told to Find Yourself

So is the answer just "be yourself"? It's a lovely idea, but it raises an awkward question. Who decides who you are?

Pull that thread and it unravels fast. Your taste, your gut, your sense of what matters are all shaped by your family, your friends, the videos you watched when you were fourteen. There's no clean, untouched version of you waiting at the bottom to be discovered.

This is where Jesus says something different. He doesn't tell you to go and find the real you. He talks about you already being salt, like it's a fact rather than a target. Elsewhere, scripture has God say, "Before I formed you in the womb I knew you" (Jeremiah 1:5). Before your family, before your culture, before anyone told you who to be, you were known. There's a version of you that culture didn't create, which means culture can't take it away either. It was given to you.

The Man Who Turned Into the Hulk

Not long after that escalator, Matt found himself on the other side of the bystander effect.

He was one of the first to reach a bad car crash. He pulled over, got to the worst of it, and needed help fast. A crowd had gathered. Every one of them would have helped. They wanted to. But they just stood there.

So Matt did the one thing the research taught him. He didn't shout "somebody help", because somebody is nobody. He pointed at one man, the biggest bloke he could see, and said, "You — I need you to get in that car." And something extraordinary happened. This nervous, unsure man sprang to life and, asking permission first, literally ripped the car door clean off. He turned into the Hulk.

Here's the thing. He could always do that. He had it in him the whole time. He was just waiting for one person to break the spell and call him into it.

He needed salt to amplify the flavour.

You don't have to rescue the room single-handedly. You don't need to win it or have a majority on side. You just have to be the one grain of salt that brings out the flavour in everyone else.

A City That Was Never Meant to Hide

Jesus goes on to say:

"You are the light of the world. A city set on a hill cannot be hidden... let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven." — Matthew 5:14–16 (ESV)

Let your light shine. Not so people admire you. Not so you change every room. So that the good they see makes them curious about God. The point of the flavour you bring is that the curiosity points straight past you to him.

Matt and Sharon have known a couple for almost twenty years who do exactly this. What they've been through is genuinely hard, and yet they remain some of the sweetest, most inspiring people you could meet. Not because life is sorted, far from it. But because they bring a distinct flavour to every room they walk into, right where they are.

One Conversation This Week

Jesus never asked anyone to win the room, be the loudest in it, or make everything awkward. The command is gentler and simpler than that. Don't walk past. Don't hide what you already are.

So here's the challenge from Sunday. Pick one conversation this week where you don't make yourself smaller to fit in. Let one true thing about you stay in the room — your faith, your conviction, your kindness, whatever it is. Don't file it off. Let the salt do its thing.

And watch what happens. When people taste something genuinely different, they don't end up staring at you. They start asking about the One you point to.

You're not here to blend in. You're here to change the flavour of the room.
