How do we know the importance of rebuking false religion?

The imperative to rebuke false religion, as seen in Titus 1:13, is to ensure that God's people are sound in their faith. False teachings distort the character of God, the nature of man, and the plan of salvation. By firmly addressing and correcting these errors, we protect the integrity of the gospel message and uphold the holiness of God. Sharp rebuke is not merely for discipline but is an act aimed at restoration to the truth, serving to guide believers back to the central message of Christ and His work. The proper approach to confronting falsehood is rooted in Scripture, aiming to draw people toward eternal truths rather than erroneous fables.
