We usually understand a shepherd to be one who leads a flock of sheep and protects it from harm. But in Revelation, the author proclaims “the Lamb at the center of the throne” to be the shepherd of the multitude of worshipers from all nations. The worshipers are praising this Lamb whom they follow and the Lamb “will guide them to springs of the water of life.” (Rev. 7: 17) Their white robes have been made white in the blood of this Lamb because the Lamb has lead his followers through the ordeal. This is an odd sort of shepherd since normally it is the job of the shepherd to protect the flock from danger, not lead the flock into it.
In John 10, often referred to as the Good Shepherd Discourse, Jesus claims that he is the true shepherd who protects his sheep, even to the extent of laying his life down for his sheep. (Jn. 10: 11) Jesus is not only the leader, but he is the gateway into the fold, the only gateway safe from thieves who come to destroy. When Jesus says: “My sheep hear my voice. I know them, and they follow me,” (Jn. 10: 27) he is attesting to a much more intimate relationship between himself and the sheep than is usually the case. As the Good Shepherd, Jesus is not just leading us, his flock, externally by walking in front of us, Jesus is leading us from within, speaking in a voice that we learn to hear as quite distinct from bandits and robbers who come to destroy or hired hands who run away when there is danger.
Early in John’s Gospel, John the Baptist points to Jesus and calls him “the Lamb of God.” The reason that the sheep hear their shepherd’s voice and recognize it intimately is because their shepherd is a lamb, one of them. As the Lamb of God, Jesus protects his sheep from being snatched out of his hand. (Jn. 10: 28) But what does the Lamb of God protect the sheep from? We were not protected from bandits and robbers any more than the martyrs in white robes were protected from the ordeal. What the Lamb of God protects us from is being or becoming bandits and robbers. That is, we are protected from being people who shed the blood in which the white robes of the martyrs are washed. Most important, it is precisely by being the Lamb of God that this shepherd does not attack robbers and thieves with the violence they impose on him, but instead he lays down his life, not only for those of us in the sheepfold, but for those who attack him and the flock. This raises the question: In protecting us from becoming bandits and robbers, is Jesus laying down his life to turn those of us who have become bandits and robbers from what we have become? If the Lamb of God died for sinners as St. Paul claimed many times, then that is exactly what he has done and that is why, in following the Lamb of God as our shepherd, we do the same, secure in the sheepfold of our shepherd with the multitudes from every nation.
