The Bible reveals both resuscitation and resurrection.  Resuscitation means a person who has died is brought back to life but will die again (see Matt. 27:50-53; Luke 7:15; 8:53-55; John 11:43-44; 12:9-11).  Resurrection means a person will be brought back to life with a new body and will never again experience death.  Jesus was the first Person to be resurrected (John 20:1-18; 1 Cor. 15:3-4; Rev. 1:5).  In the future, Jesus will resurrect Christians at the time of the Rapture (1 Cor. 15:51-53; 1 Thess. 4:14-17), OT saints (Job 19:25-27; Ezek. 37:21-25; Dan. 12:1-2; Matt. 19:28), saints who were martyred during the Tribulation (Rev. 20:4), and finally all unbelievers at the end of the Millennium (Rev. 20:5). 

What happens between death and resurrection?  Some teach that when a person dies, the soul enters into a state of unconscious sleep, unaware of anything, until the time of future resurrection.  However, the Bible teaches that the soul separates from the body at death (Eccl. 12:7), and continues in a state of consciousness.  Examples include Lazarus and the Rich man (Luke 16:19-31), and Moses and Elijah who appeared alive at Jesus’ transfiguration (Mark 9:1-4).  Further, when talking to the thief on the cross, Jesus said, “Truly I say to you, today you shall be with Me in Paradise” (Luke 23:43).  Since the thief was going to die physically, Jesus must have been referring to his soul, which has consciousness after physical death.  This reality is promoted by Paul, who preferred to be absent from his body in order to be present with Christ (2 Cor. 5:8; Phil. 1:23).
