Leaving a Bible believing church full of sinners just because of sin, is a sin.

Quote Source – Jeff Hilles

That line ought to sting a little. We’ve all felt the itch to leave somewhere — a Bible study that got awkward, a church board meeting that went sideways, a pew neighbor whose opinions grated. But it’s something most of us would rather not look at straight on: the reason we’re leaving might be the very reason we joined a church in the first place.

The Church Was Never a Museum for the Righteous

Somewhere along the way a lot of us picked up the idea that a good church is a clean one — tidy people, tidy marriages, tidy testimonies. Scripture never promises that. Jesus told the Pharisees flat out why He kept company with tax collectors and sinners: “Those who are well have no need of a physician, but those who are sick” (Matthew 9:12). A Bible-believing church isn’t a showroom of finished products. It’s a field hospital. Paul didn’t write to the Corinthians because they had it together — he wrote because they didn’t, and he kept calling them saints anyway.

Romans 3:23 isn’t a verse we quote about other people. It’s the room we’re all standing in. “For all have sinned and fall short of the glory of God.” If sin in the pews is grounds for leaving, there’s no church left to attend — including the one you’d land in next Sunday.

Grace Doesn’t Come with an Exit Clause

Here’s the uncomfortable math: if I received grace while I was still a sinner, and I did, then withholding fellowship from other sinners is a strange way to say thanks. Leaving because the church is full of flawed people isn’t discernment. It’s forgetting your own file.

And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near. [Hebrews 10:24-25]

Notice the command isn’t “meet together until it gets uncomfortable.” It’s a call to stir each other up, not to walk out when someone needs stirring. That’s slow, unglamorous work. It doesn’t photograph well. But it’s the actual job description of a church member.

When Leaving Actually Is Warranted

None of this means every departure is sin. A church that abandons Scripture, tolerates unrepentant false teaching, or refuses to practice discipline as Matthew 18 outlines has left the category this quote is even talking about. That’s not “a Bible-believing church full of sinners” anymore — that’s something else wearing the name. The quote is aimed at a narrower, more common failure: leaving a faithful church because its people are, in fact, people.

Staying Is a Form of Confession

Every Sunday you stay in a congregation of sinners, you’re preaching a small sermon to yourself: I need grace too. That posture is harder to fake than a worship set or a well-organized small group. It’s also, oddly, where sanctification actually happens — not in the church you imagine, but in the one that keeps annoying you and keeps needing you anyway.
