John 16:20-22

20Very truly, I tell you, you will weep and mourn, but the world will rejoice; you will have pain, but your pain will turn into joy.21When a woman is in labor, she has pain, because her hour has come. But when her child is born, she no longer remembers the anguish because of the joy of having brought a human being into the world.22So you have pain now; but I will see you again, and your hearts will rejoice, and no one will take your joy from you.
