When Jesus rose from the dead 3 days after He was crucified, it signified that God the Father accepted the sacrifice of God the Son for our sin. Jesus resurrection means that our sins have been forgiven and the price has been paid. Just as Christ rose from death, one day all those who trust in Christ will also rise from death. When Christ returns, He will judge the living and the dead. The physical resurrection of Jesus teaches us that in the end, all those who trust in Christ will also be raised from death, and restored bodily.
The book of Revelation teaches that in the end, the physical world will be restored and our bodies will be glorified. The new heavens and the new earth is the restoration of what God intended in the beginning. In Genesis, Eden was God’s temple – a powerful image of heaven and earth meeting in beauty. God’s intention was that humanity would flourish throughout the earth, reflecting His nature. In the end, God’s intention will be restored. In the meantime, united to Christ, we Christians are full of God’s Spirit as His “mobile temples”, enjoying Him and glorifying Him in all we do until Christ returns to restore all things and raises us from death to enjoy it!
For Christians, the end is not darkness and death but life with God. I Corinthians 15:42-49
