John 15: 26 -- John 16: 1-4, Counselor, Advocate

Jesus has told the disciples that their love for him and for each other will draw, from "the world" a certain hatred. There is a price to be paid for following the Messiah.

He then has some encouraging words about support....

John 15: 26-27, The world will hate you (if you love each other)!
“When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who goes out from the Father—he will testify about me. 
27 And you also must testify, for you have been with me from the beginning.

The disciples will receive an Advocate, the Holy Spirit, who will keep them in communication with God, so that they may successfully speak on the Messiah.

John 16: 1-4, Persecution
“All this I have told you so that you will not fall away. 
2 They will put you out of the synagogue; in fact, the time is coming when anyone who kills you will think they are offering a service to God. 
3 They will do such things because they have not known the Father or me. 

4 I have told you this, so that when their time comes you will remember that I warned you about them. I did not tell you this from the beginning because I was with you, 

The concern about the world's hatred is repeated.  Jewish believers in the Messiah will be expelled from synagogues, maybe even killed.

Even being on the Messiah's team does not offer protection from persecution, even death. There is a deeper goal here....
