Acts 7:60 (b) Christians who die are said to "fall asleep." This expression is used in regard to saints who die. The reason is plain; the body of the Christian will come forth from the grave to walk again with GOD. The body of the sinner will never be permitted to walk again in the enjoyment of GOD's blessings, but will awake to shame and everlasting contempt. He will be brought into GOD's presence for judgment at the Great White Throne, and will then be cast into outer darkness, which is the Lake of Fire.
1 Corinthians 15:6-18 (b) The meaning in this passage is similar to the one above. When we think of a person being asleep, we know that he will soon waken to live and walk with his loved ones. So it shall be with the believer. His very body will be raised and will be reunited with his circle of loved ones whom he knew on earth, and who were saved by grace. (See also "SLEEP").
