30 When he was at table with them, he took the bread and blessed and broke it and gave it to them. 31 And their eyes were opened, and they recognized him. And he vanished from their sight.
Then they told what had happened on the road, and how he was known to them in the breaking of the bread.
Something in the breaking of bread was used by God to reveal Himself more fully to those who were already interested, familiar, associated, etc.. with Him.
He is good to reveal Himself at all.
He shows His sense of humor in being revealed in something as simple and available and everyday as daily bread.
The body of Christ, the bread of Heaven.
