Lazarus and heaven
Someone asked me this question the other day and I didn't know how to answer them. The question is: "What happened to Lazarus' soul while he was in the grave? Did he experience heaven during the time that his body was in the grave? Would he then have had the opportunity to share his glimpse of heaven with those he knew after he was raised from the dead?" I told them that Scripture doesn't give us any specific information on this event, but maybe there are other passages of Scripture that can help explain the question.
As with any other human being, the body and soul of Lazarus separated when he died (Ecclesiastes 12;7). His soul went to heaven, while his body remained on earth. His soul remained in heaven while his body was in the tomb.
Resurrection is the reuniting of body and soul. That happened when Jesus summoned Lazarus to come out of the tomb (John 11:43).
Did Lazarus have memories of his short time in heaven, and did he share those memories with his family and friends? It is an interesting question, but it is one the Bible does not answer.
When it comes to Lazarus and other people who were raised from the dead in Old and New Testament times, the narratives in the Bible underscore the love and power of God and do not touch on the experiences of those involved.
