1John 3:13 Do not be surprised, my brothers, if the world hates you.
Jesus said, "If the world hates you, keep in mind that it hated me first. 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." John 15:18,19
And why did the world hate Jesus? Jesus said, "It hates me because I testify that what it does is evil." John 7:7 If you are born of God you should expect the world to hate you. And why would the world hate you? Because, just like Jesus, you are to testify that what it does is evil.
