Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with unleavened bread of sincerity and truth.
As mentioned earlier in the week, leaven symbolizes sin. In this passage, the apostle Paul describes how sin escalates and spreads—and how it can be stopped.
It doesn’t take much of a leavening agent like yeast to make bread dough expand. Likewise, a small amount of sin can spread and overtake a person’s life. When we tolerate just a little sin, problems will grow and affect others, just as yeast causes the entire lump of dough to ferment (1 Corinthians 5:6).
Malice and wickedness are two major results of sin that has grown and spread within a person’s life. One of the great lessons of the Feast of Unleavened Bread is that sin needs to be eliminated completely, so it can’t grow (verse 7).
The result of overcoming sin is a life based on “sincerity and truth.” By avoiding sin, we have nothing to hide and can live transparently.
