luke 13:18-21
The Parable of the Mustard Seed
He said therefore, ‘What is the kingdom of God like? And to what should I compare it? It is like a mustard seed that someone took and sowed in the garden; it grew and became a tree, and the birds of the air made nests in its branches.’
The Parable of the Yeast
And again he said, ‘To what should I compare the kingdom of God? It is like yeast that a woman took and mixed in with three measures of flour until all of it was leavened.’
