Jesus Appears to Mary Magdalene

10 Then the disciples went back to their homes, 11 but Mary stood outside the tomb crying. As she wept, she bent over to look into the tomb 12 and saw two angels in white, seated where Jesus' body had been, one at the head and the other at the foot.
13 They asked her, "Woman, why are you crying?"

"They have taken my Lord away," she said, "and I don't know where they have put him." 14 At this, she turned around and saw Jesus standing there, but she did not realize that it was Jesus.

15 "Woman," he said, "why are you crying? Who is it you are looking for?"
Thinking he was the gardener, she said, "Sir, if you have carried him away, tell me where you have put him, and I will get him."

16 Jesus said to her, "Mary."
She turned toward him and cried out in Aramaic, "Rabboni!" (which means Teacher).

17 Jesus said, "Do not hold on to me, for I have not yet returned to the Father. Go instead to my brothers and tell them, 'I am returning to my Father and your Father, to my God and your God.' "

18 Mary Magdalene went to the disciples with the news: "I have seen the Lord!" And she told them that he had said these things to her.

I know I'm trying to go through John from the perspective of someone who is reading the Bible for the first time, but I'm also looking for inspiration into the text. John MacArthur suggests that the reason Mary didn't recognize Jesus is the same for all people; they are prevented from recognizing him until they are called. The moment Jesus calls, "Mary", she instantly knows him. This is reminiscent of Jesus' words in chapter 10, "My sheep hear my voice, and I know them, and they follow me."
