Leaven can symbolize false doctrine or false teaching, which have the proclivity of placing us in abject bondage. We have been warned and exhorted to keep ourselves free of religious deception. With the advent of the Internet and mass communication, exposure to heresy, deception, and falsehood has exponentially increased. Our antidote to spiritual falsehood is to consume the unleavened bread of sincerity and truth. Our approach must be not only to avoid sin, but to displace it by doing God's will. We need to exercise diligence to keep ourselves free of leavening, ingesting God's Truth by means of reading the Scriptures, inculcating it deeply into our character and behavior, imitating the conduct of Jesus Christ.
