Jesus said plainly, "They hated me, they will hate you." Understanding why this is so will give us the ability to not return hate with hate, but continue to pursue love and relationship so that they may become children of God too. 

John 15:18-25 NIV

“If the world hates you, keep in mind that it hated me first. 19 If you belonged to the world, it would love you as its own. As it is, you do not belong to the world, but I have chosen you out of the world. That is why the world hates you. 20 Remember what I told you: ‘A servant is not greater than his master.’ If they persecuted me, they will persecute you also. If they obeyed my teaching, they will obey yours also. 21 They will treat you this way because of my name, for they do not know the one who sent me.22 If I had not come and spoken to them, they would not be guilty of sin; but now they have no excuse for their sin. 23 Whoever hates me hates my Father as well. 24 If I had not done among them the works no one else did,they would not be guilty of sin. As it is, they have seen, and yet they have hated both me and my Father. 25 But this is to fulfill what is written in their Law: ‘They hated me without reason.’
