1 Peter 5:8-10 warns us the devil is walking through the earth seeking prey to devour.  He and his demons are the ultimate predators and we, believers in Christ, are the ultimate prey.  If we stray from our flock and from the Good Shepherd, Jesus Christ we make ourselves vulnerable to attack.  Satan preys on the offended, the fearful, and the prideful, but we can can overcome through vigilance and remaining steadfast in the truth of God’s word.
