John 16:12-22
12 “I still have many things to say to you, but you cannot bear them now. 13 When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. 14 He will glorify me, for he will take what is mine and declare it to you. 15 All that the Father has is mine; therefore I said that he will take what is mine and declare it to you.
16 “A little while, and you will see me no longer; and again a little while, and you will see me.” 17 So some of his disciples said to one another, “What is this that he says to us, ‘A little while, and you will not see me, and again a little while, and you will see me’; and, ‘because I am going to the Father’?” 18 So they were saying, “What does he mean by ‘a little while’? We do not know what he is talking about.” 19 Jesus knew that they wanted to ask him, so he said to them, “Is this what you are asking yourselves, what I meant by saying, ‘A little while and you will not see me, and again a little while and you will see me’? 20 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. 21 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. 22 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.” (ESV)
