In the book of Revelation, Jesus is that slaughtered and stricken Passover lamb. He is, however, the Lamb exalted. He is addressed as God (compare Revelation 4:11 with 5:13). He is the One declared as "worthy." In the song sung by the elders in heaven, the worthiness of the Lamb is not based upon His deity His relationship as the Son to the Father, nor His perfect life of obedience. The reason the Lamb is praised by all of heaven and declared worthy is because of His sacrificial death. In his vision, John sees the lamb in the midst of the throne standing as though He had been slain.
