John 20

30 Jesus performed many other signs in the presence of His disciples, which are not written in this book. 31 But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.

John 17

22 I have given them the glory You gave Me, so that they may be one as We are one— 23 I in them and You in Me—that they may be perfectly united, so that the world may know that You sent Me and have loved them just as You have loved Me.

John 16

1 “I have told you these things so that you will not fall away. 2 They will put you out of the synagogues. In fact, a time is coming when anyone who kills you will think he is offering a service to God. 3 They will do these things because they have not known the Father or Me. 4 But I have told you these things so that when their hour comes, you will remember that I told you about them. I did not tell you these things from the beginning, because I was with you.
