Part 7: How to Handle Unrepentant Sin in God's Church

Nov 2, 2025    Matt Rummage

This exploration of 1 Corinthians 5 confronts us with one of the most challenging

aspects of church life: how do we handle unrepentant sin within the body of Christ? The

message centers on a shocking situation in Corinth where sexual immorality existed

that even the pagan world found unacceptable, yet the church remained arrogant rather

than broken. We're reminded that Hebrews 12:6 tells us those whom the Lord loves, He

disciplines—and sometimes that discipline comes through the actions of His people.

The sermon unpacks the difficult instruction to remove unrepentant believers from

fellowship, not as judgment but as loving discipline aimed at restoration. Using the vivid

imagery of leaven spreading through dough, we see how tolerating sin doesn't just

affect one person—it corrupts the entire community. The connection to the Passover

and Feast of Unleavened Bread reveals God's ancient pattern: redemption should

always be followed by separation from sin. Christ is our Passover Lamb, sacrificed so

we can live in purity and truth. This isn't about being better than anyone else; we're all

on level ground at the cross. But we must ask ourselves: are we repentant sinners who

acknowledge our wrongs and turn from them, or unrepentant ones who hear truth but

continue down the same destructive path? The stakes are high—not just for individual

souls, but for our witness to a watching world.
