John 16:16-20 NLT

16 “In a little while you won’t see me anymore. But a little while after that, you will see me again.”
17 Some of the disciples asked each other, “What does he mean when he says, ‘In a little while you won’t see me, but then you will see me,’ and ‘I am going to the Father’?
18 And what does he mean by ‘a little while’? We don’t understand.”
19 Jesus realized they wanted to ask him about it, so he said, “Are you asking yourselves what I meant? I said in a little while you won’t see me, but a little while after that you will see me again.
20 I tell you the truth, you will weep and mourn over what is going to happen to me, but the world will rejoice. You will grieve, but your grief will suddenly turn to wonderful joy.
