How does our approach to sin and church discipline reflect the biblical balance between restoration and purity—what does that mean for our local church’s health?

This sermon unpacks 1 Corinthians 5, where the apostle Paul shifts from theology to urgent, practical church governance. Responding to a case of church immorality—incest so shocking it stunned even those outside the faith—Paul calls the Corinthian believers to act decisively. Rather than offer excuses or remain indifferent, they are to remove the unrepentant offender from fellowship. This isn’t punitive isolation, but disciplined redemptive action: "deliver such a one to Satan… that his spirit may be saved." Furthermore, Paul emphasizes collective purity, using the imagery of removing leaven to keep the church spiritually authentic. Finally, he clarifies earlier counsel: not associating with believers who persist in unrepentant sin is an internal call to uphold holiness, not isolation from the world. Discipline, inherently difficult, remains necessary for spiritual health—both for the individual and the body.
