Lambs among wolves
Jesus Christ said to His disciples “I am sending you like lambs among wolves” in order to show them that the way won’t be easy. However, He promised them that enduring such hardships will lead them to the Kingdom of heaven. Therefore, all of his disciples and followers should evangelize His love and teachings.
Father John Nassif, priest of St. Mary Church in Chicago said in his article "lambs among wolves," that God promised to protect us from the wolves. However, children of God should take heed unless they face the danger of those wolves.
Jesus Christ also warned against the wolves who claim to be lambs. Thus, he calls his lambs to be wise enough to differentiate between true and fake lambs.
