John 16:16-33 (NIV)

16 "In a little while you will see me no more, and then after a little while you will see me."

17 Some of his disciples said to one another, "What does he mean by saying, 'In a little while you will see me no more, and then after a little while you will see me,' and 'Because I am going to the Father'?"

18 They kept asking, "What does he mean by 'a little while'? We don't understand what he is saying."

19 Jesus saw that they wanted to ask him about this, so he said to them, "Are you asking one another what I meant when I said, 'In a little while you will see me no more, and then after a little while you will see me'?

20 I tell you the truth, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy.

21 A woman giving birth to a child has pain because her time has come; but when her baby is born she forgets the anguish because of her joy that a child is born into the world.

22 So with you: Now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy.

23 In that day you will no longer ask me anything. I tell you the truth, my Father will give you whatever you ask in my name.

24 Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete.

25 "Though I have been speaking figuratively, a time is coming when I will no longer use this kind of language but will tell you plainly about my Father.

26 In that day you will ask in my name. I am not saying that I will ask the Father on your behalf.

27 No, the Father himself loves you because you have loved me and have believed that I came from God.

28 I came from the Father and entered the world; now I am leaving the world and going back to the Father."

29 Then Jesus' disciples said, "Now you are speaking clearly and without figures of speech.

30 Now we can see that you know all things and that you do not even need to have anyone ask you questions. This makes us believe that you came from God."

31 "You believe at last!" Jesus answered.

32 "But a time is coming, and has come, when you will be scattered, each to his own home. You will leave me all alone. Yet I am not alone, for my Father is with me.

33 "I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world." 

1 Peter 1:6-7 NLT So be truly glad. There is wonderful joy ahead, even though you must endure many trials for a little while. 7These trials will show that your faith is genuine. …

James 1:2-4 NIV Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, 3because you know that the testing of your faith produces perseverance. 4Let perseverance finish its work so that you may be mature and complete, not lacking anything.

Romans 5:1 (NIV) 1 Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ,

John 14:27 (NIV) 27 Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid.

John 16:33 (NIV) 33 "I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world."

John 20:19 (NIV)19 On the evening of that first day of the week, when the disciples were together, with the doors locked for fear of the Jews, Jesus came and stood among them and said, "Peace be with you!"
