Smart pigs. 
“The demons begged Jesus not to send them into eternal darkness. A large herd of pigs was feeding on a hill, and the demons begged Jesus to allow them to go into the pigs. So Jesus allowed them to do this. When the demons came out of the man, they went into the pigs, and the herd ran down the hill into the lake and was drowned.” – Luke 8:31-33
When do we get mad enough at the sin in our lives that we would rather die than let it live in us?
I think pigs are smarter than sheep. ūüėČ 
“God, examine me and know my heart;

test me and know my anxious thoughts.

See if there is any bad thing in me.

Lead me on the road to everlasting life.” – Psalms 139:23
