In the Christian faith, the events of the Crucifixion and the Resurrection of Jesus Christ are more than historical occurrences; they are the foundation of spiritual hope and salvation. The Apostle Paul, in his epistles, specifically highlights the importance of these events, articulating that without the Resurrection, the belief system of Christianity would be in vain (1 Corinthians 15:14). This article delves into the necessity of the Resurrection for salvation, the significance of Jesus as the 'firstfruits' of the resurrection, and the relationship between the Crucifixion and the Resurrection. It will also explore the imagery of Jesus as the 'Lamb of God' and its implications for the promise of eternal life.
