Why was the stone removed from Jesus' tomb?

[Biblegate]

After His resurrection, Jesus could walk through obstacles. So why did the stone need to be rolled away from His tomb?

Steve replied that the removal of the stone allowed the disciples to see the empty tomb which makes perfect sense, but also the risen Christ certainly would have convinced them also. Perhaps it was also a symbolic action by the angel to demonstrate the power of God conquers the power of darkness which says that Satan holds the power of death. In a sense a symbol of Satan's defeat at the moment he thought he triumphed.
