Then said he,
Unto what is the kingdom of God like? and to what shall I compare it?
All Commentaries on Luke 13:18 Go To Luke 13
Peter Chrysologus
AD 450
As the text says, the kingdom of God is like a grain of mustard seed, because the kingdom is brought by a word from heaven. It is received through hearing and sown by faith. It takes root through belief and grows by hope. It is diffused by profession, and it expands through virtue. It is spread out into branches. To these branches, it invites the birds of heaven, the powers of spiritual insight. In those branches, it receives them in a peaceful abode.
