Lion

Peter wrote this passage around the time the Roman emperor, Nero, was persecuting Christians. Many followers of Jesus were led to the Roman Colosseum to be mauled and torn apart by lions. Peter used that relevant picture to remind Christians that Satan, our adversary, the one called the devil, the slanderer, seeks to defeat and destroy us.

Jesus, as the Lion of the tribe of Judah, is seen as one who battles on behalf of his people. He defeated the last enemy, death itself!
