One day, a pig and a hen walk down the street. They saw a sign in front of a church saying "WE FEED THE POOR".
"What do they feed the poor with?" asked the pig.
"Bacon and eggs." the hen replied.
"...urgh! There is something wrong here!" said the pig, "What you are offering is just a contribution. But mine is a total sacrifice."
Jesus has sacrificed Himself for our sin. What can we, the followers of Jesus Christ, offer then?
