Feeding of the Five Thousand
Sorry for all the commentary quotes lately! If you are looking for a good commentary on Luke, I definitely recommend this one by Darrell Bock (see the footnote below). He has so many good thoughts that I can't help but quote him often!
Anyway, here are some good observations on the Feeding of the Five Thousand miracle. I've bolded the parts that I thought were interesting or important:
"Luke now records the only miracle that is in all four Gospels: the feeding of the five thousand (Matt. 14:13–21; Mark 6:32–44; John 6:1–15). This miracle of provision obviously indicates how Jesus meets needs. But there is a second key to the miracle, in that this provision comes through the disciples. Jesus has just commissioned them to share the kingdom message (9:1–6). They need to be aware of what they can do through Christ. Jesus shows them that they have access to his authority through his enablement.
Two other images impact this event. The provision of food is conceptually similar to two key Old Testament events, God’s provision of quail and Elisha’s provision of barley bread (Num. 11; 2 Kings 4:42–44). The picture of table fellowship also evokes images of the messianic banquet, where God’s people enjoy fellowship provided by the gracious provision of the Messiah.
The miracle has a rich tapestry of fundamental themes that weave through Jesus’ ministry: compassion, control over creation, and the ability to make provisions for life. In a sense, this is a cameo portrait of God’s grace and the offer of his presence at a table where he provides for his children."
