Many so-called Christians are self-righteous hypocrites who love to brag about their sin. For instance, often we boast to our friends how we “got back” at other people who don’t like us. When this bragging happens in church, and is tolerated, it defiles the whole church. Boasting about sin publicly in church is very dangerous, as the Apostle Paul warns us in the book of I Corinthians:
Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? (I Corinthians 5:6)
In this passage Paul is comparing sin to the yeast that bakers use to make bread. The yeast is small at first–actually it is a microscopic fungus–but it grows very quickly and spreads far and wide when the conditions are right. The same is true about sin in your church. If you allow it to go unchecked it will feed off of itself until your entire fellowship of believers is contaminated. Therefore, sin in the church should not be tolerated, and should never be publicly accepted. It should be dealt with swiftly using the Biblical guidelines.
