And again he said, Whereunto shall I liken the kingdom of God? It is like leaven, which a woman took and hid in three measures of meal, till the whole was leavened.
Luke 13: 20,21

sourdough because sourdough is easily made from nothing more than flour and water. But why would the Lord say the kingdom of God is like a woman who hid leaven in three measures of meal? What does leaven do?
