Most childhood best friendships start with something absurdly simple: One kid on the bus notices another kid reading a book and blurts, “Hey, can the girl on the cover really turn into a skunk?” The other kid confirms, they start debating what animals they’d morph into, and — flash forward 20 years — they’re toasting each other at their weddings.
Adulthood is not like that.
Somewhere between the last cafeteria Go-Gurt trade and your first LinkedIn endorsement, friendship stopped being effortless. The data backs it up: A 2024 poll from the American Psychiatric Association finds that 30% of adults say they’ve experienced feelings of loneliness at least once a week over the past year, and 10% feel lonely every single day. Kids can make friends with a stick; adults can barely make small talk in the grocery line without rehearsing first.
“When we were younger, most of our primary relationships were supported by institutions,” says Erin Lane, author of Lessons in Belonging from a Church-going Commitment Phobe. “But when you age out of institutions, it becomes a hustle to cultivate friendships on your own. They require more margin on our part to support.”
Sure, you could shrug and decide your TV is your new best friend — you already talk back to it anyway — but that would miss a major biblical throughline: Community isn’t optional. In John 13, Jesus tells his disciples to love one another the way he’s loved them.
Richard Lamb, author of The Pursuit of God in the Company of Friends, points out that Jesus didn’t just call his disciples to himself — he called them to each other. Friendship wasn’t a side quest; it was the mission.
Aristotle categorized friendship into three motives: mutual enjoyment, mutual usefulness and shared commitment to the good. Childhood friendships pedal along on the first two (think Kim Possible marathons and swapping Lunchables), but adult friendships need more of that third category: purpose. Serving together. Sacrificing together. Choosing the same destination, even if the roads there look different.
Tim Keller put it this way in The Meaning of Marriage: “Christian friendship is the deep oneness that develops as two people journey toward the same destination, helping one another through the dangers and challenges along the way.”
Sounds lofty until you realize maybe it just means driving across town to cheer your friend on — even when you’d rather be wrapped in a blanket at home.
Lane says sustaining real friendship comes down to three things: proximity, spontaneity and vulnerability. The first two are easy enough to fake: show up to church, trivia nights, or that recurring worship service enough weeks that people stop thinking you’re a ghost. Then carve a time slot each week for last-minute plans — because if you’re never free, you’ll never say yes.
Vulnerability is harder. It means letting people see the unpolished, inconvenient parts of you — not just the curated weekend self. It’s risky, but it’s Christlike.
“Healthy friendships risk showing up in the flesh,” Lane says. “That’s patterned on Jesus first and foremost: God is hungry for friendship with us, and when you’re hungry for someone, you show up in the flesh, pay attention to their lives and bear witness to them.”
And here’s the kicker: Friendship also means grace when people mess up — because they will. The Gospels are full of disciples bickering and being completely extra, and Jesus still washed their feet.
As Lane puts it, “Friendship is a practice, not a privilege. We’re in practice with one another to become our true selves and the people God has purposed us to be. We’re going to get it wrong a lot, and we need people who get that. There’s a lot of mercy in the relationship.”
If this sounds like work, that’s because it is — but the payoff is much bigger than having someone to text memes to. Healthy friendships can help you grow spiritually, emotionally and even physically.
Research from Harvard’s 85-year Study of Adult Development shows that close relationships are the strongest predictor of long-term happiness and health, beating out wealth, career success and even genetics. I
n other words, your future well-being may have less to do with your 401(k) balance and more to do with whether you have a few people you can call at 2 a.m.
So start small. Say yes more often. Risk being the one to send the invite, even if it feels awkward. Ask follow-up questions that go deeper than “How’s work?” Offer to help when someone’s moving or sick or in a tight spot. Look for ways to be the friend you’re hoping to find.
Making friends in your 20s isn’t about recreating the school-bus magic; it’s about showing up, making space and risking being known. And the timing might actually be better now than when you were a kid — because being an old friend takes actual wisdom, patience and a little grit. The kind you don’t get from trading Gushers.
