John 16:20-22

Truly, truly, I say to you, you will weep and lament, but the world will rejoice. You will be sorrowful, but your sorrow will turn into joy. When a woman is giving birth, she has sorrow because her hour has come, but when she has delivered the baby, she no longer remembers the anguish, for joy that a human being has been born into the world. So also you have sorrow now, but I will see you again, and your hearts will rejoice, and no one will take your joy from you.
