Jesus is our Shepherd, and the sheep do not need to fear the wolves as long as they stay close to the Shepherd

John 10:28-30 

And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand. I and my Father are one.
