How do we know that resurrection is central to Jesus' authority?

In Acts 2:22-24, Peter emphasizes that Jesus was 'approved of God among you by miracles and wonders and signs.' The resurrection was a pivotal proof of His authority; it demonstrated not only His power over death but His ability to fulfill the prophecies about the Messiah. When He declared in John 2:19, 'Destroy this temple, and in three days I will raise it up,' He was not merely speaking of the physical structure but foreshadowing His own resurrection, which is the cornerstone of Christian faith and the confirmation of His divine nature and mission.
