John 20: Mary Magdalene witnesses Jesus resurrected

 In Luke 8:2 we read: "Mary who was called Magdalene, from whom seven demons had gone out". 

She must have been a tormented woman, seeking her auto destruction, yelling obscenities with no control. However, Jesus transformed her life. She was certain that Jesus was much stronger than her demons, thus she followed Jesus from Galilee to Jerusalem with the disciples.

Mary Magdalene went to tomb where Jesus was buried and saw that the the stone (as a door) was removed from the entrance. Due to the Sabbath, Jesus body was not properly handled for burial. She (with others) went there to prepare his body.
In John gospel, Mary Magdalene is the first one to see Jesus resurrected. We read:

13-14 “They took my Master,” she said, “and I don’t know where they put him.” After she said this, she turned away and saw Jesus standing there. But she didn’t recognize him.
15 Jesus spoke to her, “Woman, why do you weep? Who are you looking for?”
She, thinking that he was the gardener, said, “Sir, if you took him, tell me where you put him so I can care for him.”
16 Jesus said, “Mary.”
Turning to face him, she said in Hebrew, “Rabboni!” meaning “Teacher!”
17 Jesus said, “Don’t cling to me, for I have not yet ascended to the Father. Go to my brothers and tell them, ‘I ascend to my Father and your Father, my God and your God.’”
18 Mary Magdalene went, telling the news to the disciples: “I saw the Master!” And she told them everything he said to her.

Jesus is the Logos that came from heaven. After resurrection Jesus is returning to the Lord, the Father. Imagine if Jesus hadn't risen from the death. Would we believe in Jesus as the Messiah? The resurrection is the great miracle that testifies that Jesus is the Messiah, the Son of God, the lamb of God that takes away our sins. Not only that, but the the power that resurrected Jesus is the power that will resurrect me after my death. Through the resurrection of Jesus we can rest in peace.
