Regardless of all the deficiencies (or perceived deficiencies) of sheep, the real issue is THE BIG BAD WOLVES prowling about to devour the sheep (on which this OP is focused).
What we find on radio and television is a good example, where they also fleece the sheep.
Yea thats true, im thinking someones trying to blame sheep for not being wolves. GOd is talking about the nature of animals, and He does not actually say sheep are stupid. Thats just peoples misperception.
What sheep represent to God is His loving kindness, His faithfulness and His sacrifice. Because our God is a good shepherd. Not a wolf.
Another thing about animals is that people think to have cunning or craftiness like a snake is good, but actually people can be taken in by their own craftiness.
Gods ways are higher than ours, we might lean on our own understanding and think we are clever. But actually its not, its better to lean on God, because His ways are not our ways. So sheep, following a shepherd, are always kept safe IF the shepherd is good...example being JESUS. We arent left on our own because we have Jesus.
Now I can tell you how STUPID I was before I followed Jesus. I just thought I could go my own way, but I always got lost. And if I followed anyone else, that was also stupid too. One has to train ones ears to listen only to Jesus. What everyone else says is really nothing. If you decide to follow Jesus, theres no turning back. So dont let others distract you.
Wolves are brute beasts designed to destroy, they arent to God of any value in their nature like sheep are.
Why is this because wolves are also selfish creatures and can be vicious. When Jesus says feed my sheep, feed my lambs, really think about what he means. He doesnt mention any other animals. Why did John the baptist say Jesus was the Lamb of God? Because way back in Genesis, one gave their life so adam and eve could be covered.
