This striking proverb affirms the cleansing power of discipline that reaches deep. Just as a wound that is treated, though painful, cleans out infection, so does real correction reach and cleanse the inner person. This does not glorify cruelty — it teaches that genuine discipline, even when painful, has a purifying, redemptive purpose that shallow correction never achieves.
Memory phrase: Correction cleanses from inside.
Talk about it: Why might a loving correction sometimes feel painful?
Prayer: God, help me receive correction that makes me truly better.
