Was the stone was rolled away so that the Lord could come out?

 No,  He did not have any need of that.  At one point the disciples were hidden away in a room where the windows and doors were closed and locked and Jesus Christ just walked right in.   He needed no door, the stone was rolled away so that we could look in. The empty tomb is the greatest evidence of the resurrection of Jesus Christ in all of history.  Some say it was the wrong tomb. But the Pharisees and the Sadducees certainly would have found the right tomb, and produced the dead and decaying body of Jesus Christ.  But they were unable to.              The empty grave is proof that our Savior is no longer dead but is now risen as He has said. By Jesus resurrection, he demonstrated that he had greater power than sin and death.  Jesus is an overcomer and that is His will for our lives too.
