John 20:
But Mary stood weeping outside the tomb. As she wept, she bent over to look into the tomb; and she saw two angels in white, sitting where the body of Jesus had been lying, one at the head and the other at the feet. They said to her, “Woman, why are you weeping?” She said to them, “They have taken away my Lord, and I do not know where they have laid him.” When she had said this, she turned around and saw Jesus standing there, but she did not know that it was Jesus. Jesus said to her, “Woman, why are you weeping? Whom are you looking for?” Supposing him to be the gardener, she said to him, “Sir, if you have carried him away, tell me where you have laid him, and I will take him away.”
Jesus said to her, "Mary." She turned and said to him in Hebrew, "Rab-bo'ni!" (which means Teacher).
Mary was weeping so hard that she could not see/recognize Jesus when he was right there standing with her.
Dear Jesus in moments of defeat and sorrow help us to hear your voice calling our names, strengthening us to follow your call.
