What is the significance of leaven in the Christian life?

In the parable of leaven, found in Luke 13:21, Jesus illustrates how the kingdom of God works within the heart of believers. Just as leaven permeates dough, the work of grace begins small, often unnoticed, and gradually influences the entire life of a person. This signifies that genuine transformation is inevitable when the Holy Spirit operates in an individual’s life. Believers are encouraged to recognize and nurture these small beginnings of grace, as they will lead to a profound change in character and behavior.
