How do we know that Jesus' resurrection was significant?

The resurrection of Jesus is central to the Christian faith, affirming the effectiveness of His sacrifice. In Psalm 30, Jesus speaks of being lifted up, reflecting His confidence in the Father to raise Him after enduring the cross. This act is not only a demonstration of His power but also a fulfillment of God's covenant promise. Through His resurrection, believers are assured that death does not have the final word, and they are granted hope and new life through Him, which is a cornerstone of the Gospel.
