Why do people sometimes act "fake" or hypocritical in church?

The observation that people sometimes act "fake" or hypocritical in church is, unfortunately, often true, and it stems from the universal human struggle with sin and the pressure to perform. The church is a hospital for sinners, not a museum for saints. This inauthenticity often arises from a fear of being judged, a desire for approval, or a misunderstanding that Christian life requires perfection rather than genuine repentance. The remedy is a culture of grace and vulnerability, where confession and humility (1 John 1:9) are valued more than appearances.
