Luke 12:46
Then Jesus asked, What is the kingdom of God like? What shall I compare it to? It is like a mustard seed, which a man took and planted in his garden — the mustard seed's growth from the smallest of seeds to a tree where the birds of the air perch in its branches (echoing Daniel 4:12 and Ezekiel 17:23) communicates the kingdom's disproportionate expansion. The birds-of-the-air are the nations sheltering in the kingdom's provision.
