Jesus’ body truly died and remained in the tomb for three days, showing the reality of His death. His soul, however, departed and went to Paradise, as He promised the repentant thief on the cross. In the Paradise side of Sheol, Jesus proclaimed victory over sin and death, as He eternally defeated them with His death on the cross. Jesus did not offer a second chance of salvation after death. Therefore, during those three days, Jesus was in Paradise, alive in spirit, while His body awaited resurrection.
The most likely scenario is that Jesus spent the entire time between His death and resurrection in the heavenly realm. Though the Bible does not specify the details of what took place with Jesus during this time period, what is made clear points to Jesus being in "paradise" after his death and prior to His resurrection in His physical body on the third day.
Mormons (Latter-day Saints) teach that after His death, Jesus went to the spirit world, where He organized the preaching of the gospel to those who had died without hearing it. They believe He did not personally preach to everyone but delegated righteous spirits to carry His message so that all could have the chance to accept or reject the gospel before judgment. The Mormon teaching that Jesus organized missionary work in the spirit world is unbiblical because Scripture never says He set up a second chance for salvation after death. Hebrews 9:27 makes it clear that “it is appointed for man to die once, and after that comes judgment,” meaning our decision about Christ must be made in this life. While 1 Peter 3:18–20 mentions Jesus proclaiming victory to imprisoned spirits, this is not the same as offering salvation, and no verse suggests He delegated evangelism to others in the afterlife. Further, God made clear the way of salvation even in the Old Testament: by faith in God and the promised Messiah. Now that Jesus came, died, and rose again, salvation is still by faith in Him. Once we die, our eternal destiny is sealed. There are no second chances after death.
Jesus’ promise to the thief on the cross assures us that death cannot separate believers from God, because those who trust in Christ immediately enter His presence in paradise. Jesus’ time in the heavenly realm shows that even in death, Jesus remained Lord over all creation, fully alive in spirit while His body awaited resurrection. He declared victory over sin and the grave through His death. Those who trust in His death and resurrection for the forgiveness of sins can also face death without fear, knowing that our souls are safe with Him and that our bodies too will one day be raised in glory. Our faith is not shaken because the same God who raised Jesus will also raise us to eternal life in His presence.
