Luke 13:18-21

18Then Jesus asked, “What is the kingdom of God like? To what can I compare it? 19It is like a mustard seed that a man tossed into his garden. It grew and became a tree, and the birds of the air nested in its branches.”

20Again He asked, “To what can I compare the kingdom of God? 21It is like leaven that a woman took and mixed into three measures of flour, until all of it was leavened.”
