Gospel according to Saint Luke 13:18-21
Jesus said, “What is the Kingdom of God like? To what can I compare it? It is like a mustard seed that a man took and planted in the garden. When it was fully grown, it became a large bush and the birds of the sky dwelt in its branches.” Again he said, “To what shall I compare the Kingdom of God? It is like yeast that a woman took and mixed in with three measures of wheat flour until the whole batch of dough was leavened.”
