In his first letter to the Thessalonians, Paul asked Christians not to grieve like others over their members who have fallen asleep because those who have fallen asleep will rise again. Paul was reassuring the Thessalonians that death is not the end for believers in Jesus Christ. Instead, those who have died in Christ will rise again and be reunited with Him. Paul's message was a message of hope and comfort to those who were mourning the loss of their loved ones. It is not because sleep is a natural way of taking rest after a day's job, nor is it because fallen asleep is an inescapable lot of everybody. It is also not because only sinners fall asleep; hence no mourning for them. Paul's message was based on the Christian belief in the resurrection of the dead and the hope of eternal life in Christ.
