The swoon theory is one of Satan's oldest lies concerning the Resurrection. This theory proposes that Jesus did not rise from the dead, because He never really died. Instead, Jesus went into a deep coma or "swoon" from the severe pain and trauma of the Crucifixion. Then, in the cool atmosphere of the tomb, Christ revived, somehow escaped the strips of cloths that were wrapped tightly upon Him, and then appeared to His disciples.
The swoon theory flies in the face of the facts. You see, the Roman guards were experts at execution and would be put to death if they allowed a condemned man, like Christ, to escape death. The guards were certain Jesus was dead, because when they thrust a spear into His side, it brought forth blood and water. This was their final proof of His death because this occurs when the heart stops beating.
