What does the Bible say about the significance of Jesus's resurrection?

The resurrection of Jesus is a cornerstone of Christian doctrine, as expressed in John 14:19, where Jesus states, 'Because I live, you shall live also.' This declaration affirms the eternal life that believers receive through their union with Christ. His resurrection signifies victory over death and the assurance that believers, who are identified with Him, will also share in this life. Romans 5:10 reinforces this by indicating that believers are reconciled to God through His death, and because of His life, they are saved. This promise encompasses both spiritual resurrection now and eternal life to come, establishing the hope and assurance essential to the Christian faith.
