How do we know the Feast of Unleavened Bread is significant?

The Feast of Unleavened Bread, which follows the Passover, represents the sanctifying work of faith in Christ. Spanning seven days, as noted in Leviticus 23:6, it symbolizes a life free from sin, as leaven often represents sin in Scripture. This feast indicates that while the Passover celebrates redemption through Christ's blood, the Unleavened Bread points to the resulting spiritual life, where believers are called to live in holiness. It underscores the necessity of faith that tastes and experiences the fullness of salvation, evidencing how grace truly transforms a believer's life.
