Question: "What does the Bible say about soul sleep?"

Answer: “Soul sleep” is a belief that after a person dies, his/her soul “sleeps” until the resurrection and final judgment. The concept of “soul sleep” is not biblical. When the Bible describes a person “sleeping” in relation to death (Luke 8:52; 1 Corinthians 15:6), it does not mean literal sleep. Sleeping is just a way to describe death because a dead body appears to be asleep. The moment we die, we face the judgment of God (Hebrews 9:27). For believers, to be absent from the body is to be present with the Lord (2 Corinthians 5:6-8; Philippians 1:23). For unbelievers, death means everlasting punishment in hell (Luke 16:22-23).

Until the final resurrection, though, there is a temporary heaven—paradise (Luke 23:43; 2 Corinthians 12:4) and a temporary hell—Hades (Revelation 1:18; 20:13-14). As can be clearly seen in Luke 16:19-31, neither in paradise nor in Hades are people sleeping. It could be said, though, that a person’s body is “sleeping” while his soul is in paradise or Hades. At the resurrection, this body is “awakened” and transformed into the everlasting body a person will possess for eternity, whether in heaven or hell. Those who were in paradise will be sent to the new heavens and new earth (Revelation 21:1). Those who were in Hades will be thrown into the lake of fire (Revelation 20:11-15). These are the final, eternal destinations of all people—based entirely on whether or not a person trusted in Jesus Christ for salvation.

Present-day defenders of soul sleep include the Seventh Day Adventist church, Jehovah’s Witnesses, Christadelphians, and others.

Speaking of the Gulf in Heaven… it was Lazarus

19There was a certain rich man, which was clothed in purple and fine linen, and fared sumptuously every day: 20And there was a certain beggar named Lazarus, which was laid at his gate, full of sores, 21And desiring to be fed with the crumbs which fell from the rich man's table: moreover the dogs came and licked his sores. 22And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried; 23And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom. 24And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame. 25But Abraham said, Son, remember that thou in thy lifetime receivedst thy good things, and likewise Lazarus evil things: but now he is comforted, and thou art tormented. 26And beside all this, between us and you there is a great gulf fixed: so that they which would pass from hence to you cannot; neither can they pass to us, that would come from thence. 27Then he said, I pray thee therefore, father, that thou wouldest send him to my father's house: 28For I have five brethren; that he may testify unto them, lest they also come into this place of torment. 29Abraham saith unto him, They have Moses and the prophets; let them hear them. 30And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent. 31And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
