John 15 v18-27 speaks of how Christ was hated without cause when He was on earth, and reminds Christian's that we too will face hatred from the world when they obey Jesus and fulfil his commands.

John 15:18–27

The Hatred of the World

18 “If the world hates you, know that it has hated me before it hated you. 19 If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you. 20 Remember the word that I said to you: ‘A servant is not greater than his master.’ If they persecuted me, they will also persecute you. If they kept my word, they will also keep yours. 21 But all these things they will do to you on account of my name, because they do not know him who sent me. 22 If I had not come and spoken to them, they would not have been guilty of sin,¹ but now they have no excuse for their sin. 23 Whoever hates me hates my Father also. 24 If I had not done among them the works that no one else did, they would not be guilty of sin, but now they have seen and hated both me and my Father. 25 But the word that is written in their Law must be fulfilled: ‘They hated me without a cause.’

26 “But when the Helper comes, whom I will send to you from the Father, the Spirit of truth, who proceeds from the Father, he will bear witness about me. 27 And you also will bear witness, because you have been with me from the beginning.
