Seven Holy Sleepers:   when the Emperor Decius had the seven Christian soldiers entombed alive, God miraculously kept them in miraculous sleep for over 200 years.  At the time they awoke they provided living witnesses to the reality of the resurrection of the body.  God’s timing is always perfect:  too bad we often doubt it.
