So, the readings are:
Genesis 32: 22-31 - Jacob wrestling at Jabbok
Romans 9: 1-5 - a rather odd bit of Paul asserting his Jewish identity but also talking of being cut off!
Matthew 14: 13-21 - Feeding of 5000 - Jesus has compassion & heals & then feeds the people.
First thoughts - I love the story of Jacob's wrestling - it's such a great story of how the slippery little Jacob with all his tricks & wiles (remember the mess of pottage?) finally meets his match & is left blessed but with a limp & emerges as the 'patriarch', Israel.
Maybe the link with the gospel reading is of how God blesses us - not cheaply but at a cost. Jesus' miracles were not to impress, but out of compassion for people.
I need to understand the Romans passage better - will do some reading around...
