In this 2.5 minute video clip, evangelist Bobby Conway of The One Minute Apologist rightly declares that the Passover Lamb described in the Old Testament foreshadowed Jesus of Nazareth. At the end of the clip, he recommends a book by Walter Kaiser, which I have also recommended.
Because the Passover presaged Christ, John the Baptist could refer to his cousin Jesus as “the Lamb of God” (John 1:29,36) and the apostle Paul could say “Christ our Passover is sacrificed for us” (1 Corinthians 5:7).
Similarly, the entire Old Testament testifies about Christ (John 5:39, 46; Luke 24:25-27, 44-48; 2 Timothy 3:14-15). We would do well to pay more attention to biblical themes like the Passover so that we might grow in the grace and knowledge of our Lord and Savior Jesus Christ.
