Jesus himself said no.
People sometimes say these stories encouraged their faith or the faith of someone they know. But I think they actually diminish biblical faith by elevating claims of a supernatural experience over the substance of the Scriptures. Most of these claims of seeing into heaven focus on earthbound concerns and stunted human desires that lack what the Bible describes as the heart of heaven—the glory of God, the Lamb who was slain, on the throne of the universe. In embracing these stories we’re saying the Bible is simply not enough, that someone’s mystical experience is needed to verify or “make real” what God has said. But saving faith is putting all our hopes in who God is and what God has said as revealed in the Bible. It is being confident of what we can’t see (John 20:29; Hebrews 11:1), not being convinced by something someone else supposedly saw.
Interestingly, Jesus himself spoke of the uselessness of such testimony for generating genuine faith. Jesus told a story about a rich man in the place of the dead who calls out to “Father Abraham” to go and warn his brothers so they will not end up in the place of torment (Luke 16:19-31). The rich man wants someone who has died and gone to heaven to come back to life and tell about his experience so that his family members will believe what the Scriptures teach about the consequences of failing to become united to Christ by faith.
In Jesus’ story Father Abraham says, “If they won’t listen to Moses and the prophets, (meaning, if they won’t believe what the Bible says) they won’t listen even if someone rises from the dead.” Jesus is saying that everything we need to put our faith in the promises of God, everything we need to find comfort and hope regarding the life beyond this life, can be found in the Scriptures.
