As we have seen in the book of Acts, the time between the resurrection of Christ and the destruction of Jerusalem in AD 70 was a time of overlap between the old and new covenants. Christ Himself was the sacrifice of the new covenant, which was better by far than the blood of bulls and goats. Christ is the lamb of God who takes away the sin of the world and our text today is designed in order that we would join with those heavenly voices saying, “Worthy is the Lamb that was slain” (Revelation 5:12).
