What is the significance of the sparrow?
The sparrow imagery comes from Matthew 10:29-31 and Luke 12:6-7, when Jesus is talking about how much God cares for each of us: 29 Are not two sparrows sold for a [1] cent? And yet not one of them will fall to the ground apart from your Father. 30 But the very hairs of your head are all numbered. 31 So do not fear; you are more valuable than many sparrows.
