The Bible has a lot to say about leaven and its effects upon the Believer. Leaven as an ingredient gives a false sense of growth. In the New Testament there are at least six types of leaven spoken about and we will be exploring them in detail, in order to ensure that our lives are completely free of the first five, and completely influenced by the sixth! These types of leaven include the following: The leaven of the Pharisees; The leaven of the Sadducees; The leaven of the Galatians; The leaven of Herod; The leaven of the Corinthians. However, the Leaven of the Kingdom of God, is the only type of leaven that has the power and capacity to bring about true growth and lasting change to our lives.
