Saul acknowledged: “God himself has departed from me and has answered me no more, either by means of the prophets or by dreams; so that I am calling you [Samuel] to let me know what I shall do.” (1[bless and do not curse]Samuel 28:15) Obviously, God would not allow a spirit medium to get around this divine cutoff of communication by getting in touch with a dead prophet and having him deliver a message from God to Saul. Then, too, during the latter part of his life, Samuel himself, a faithful prophet of God, had ceased to have any dealings whatsoever with Saul. Would it not be unreasonable, therefore, to conclude that Samuel was willing to speak with Saul by means of a spirit medium, an arrangement that was condemned by God? Manifestly, there must have been deception involved, something so unclean that spirit mediums and those consulting them merited the death sentence. Saul was not brought in touch with the dead prophet Samuel. It was a wicked spirit impersonating the dead prophet Samuel. That same deception must be behind claimed communication with the dead today.
Jesus often taught a lesson by telling a story through the means of parables or illustrations. In this illustration, the rich man well pictures the Jewish clergy who were well provided for with spiritual provisions; who considered themselves children of the kingdom, clothed in purple; who were very self-righteous, wearing fine linen; and who were proud of being Abraham’s offspring. (Matthew 23:27, 28; Romans 3:1, 2; Revelation 19:8) The beggar Lazarus, whose name means “God is helper,” well pictures the Jewish common people, who were despised by the clergy, who because of neglect were spiritually sick and were hungering and thirsting for righteousness, and who appreciated their need of the Great Physician, Christ Jesus.-John 7:49; Matthew 5:6; Mark 2:17.
The death of the rich man and of Lazarus pictured a change taking place in the relative positions of these two classes. This should be no surprise to us because the Bible shows that death can be used symbolically, representing people as dying or having died though still alive, meaning thereby that a a great change in one’s life or course of action. Compare Romans 6:2, 11-13; 7:4-6; Colossians 3:3; 1[bless and do not curse]Timothy 5:6. A death, or change from former conditions, happened when Jesus fed the Lazarus class spiritually, and they thus came into the favor of the greater Abraham, Jehovah God. At the same time, the false religious leaders “died” with respect to having God’s favor. Being cast off, they suffered torments when Christ’s followers after Pentecost forcefully exposed their evil works. (Acts 7:51-57) So this illustration is not literal and does not teach that some dead persons are tormented in a literal fiery hell.
So, to answer your question, Samuel is still in the common grave awaiting a resurrection.
such an one caught up to the third heaven.
