1. Jesus walked through walls, or atleast He suddenly stood inside the room, so why did an angel have to take away the grave stone? And even if He couldnt walk through a stone, He could walk on water, raise the dead, change water into wine and calm the storm, but needed help with the stone?
John 20 Revised Standard Version (RSV)
The Resurrection of Jesus
20 Now on the first day of the week Mary Mag′dalene came to the tomb early, while it was still dark, and saw that the stone had been taken away from the tomb. 2 So she ran, and went to Simon Peter and the other disciple, the one whom Jesus loved, and said to them, “They have taken the Lord out of the tomb, and we do not know where they have laid him.” 3 Peter then came out with the other disciple, and they went toward the tomb. 4 They both ran, but the other disciple outran Peter and reached the tomb first; 5 and stooping to look in, he saw the linen cloths lying there, but he did not go in. 6 Then Simon Peter came, following him, and went into the tomb; he saw the linen cloths lying, 7 and the napkin, which had been on his head, not lying with the linen cloths but rolled up in a place by itself. 8 Then the other disciple, who reached the tomb first, also went in, and he saw and believed; 9 for as yet they did not know the scripture, that he must rise from the dead. 10 Then the disciples went back to their homes.
Mark 16 Revised Standard Version (RSV)
The Resurrection of Jesus
16 And when the sabbath was past, Mary Mag′dalene, and Mary the mother of James, and Salo′me, bought spices, so that they might go and anoint him. 2 And very early on the first day of the week they went to the tomb when the sun had risen. 3 And they were saying to one another, “Who will roll away the stone for us from the door of the tomb?” 4 And looking up, they saw that the stone was rolled back—it was very large. 5 And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe; and they were amazed. 6 And he said to them, “Do not be amazed; you seek Jesus of Nazareth, who was crucified. He has risen, he is not here; see the place where they laid him. 7 But go, tell his disciples and Peter that he is going before you to Galilee; there you will see him, as he told you.” 8 And they went out and fled from the tomb; for trembling and astonishment had come upon them; and they said nothing to any one, for they were afraid.
Luke 24 Revised Standard Version (RSV)
The Resurrection of Jesus
24 But on the first day of the week, at early dawn, they went to the tomb, taking the spices which they had prepared. 2 And they found the stone rolled away from the tomb, 3 but when they went in they did not find the body.[a] 4 While they were perplexed about this, behold, two men stood by them in dazzling apparel; 5 and as they were frightened and bowed their faces to the ground, the men said to them, “Why do you seek the living among the dead?
6 Remember how he told you, while he was still in Galilee, 7 that the Son of man must be delivered into the hands of sinful men, and be crucified, and on the third day rise.” 8 And they remembered his words, 9 and returning from the tomb they told all this to the eleven and to all the rest. 10 Now it was Mary Mag′dalene and Jo-an′na and Mary the mother of James and the other women with them who told this to the apostles; 11 but these words seemed to them an idle tale, and they did not believe them
None of the texts says how the stone was moved. I always thought it was an earthquake that moved it.
