“Do not be surprised, brothers, that the world hates you.” (ESV – Read the chapter)
Make no mistake: If you are a follower of Jesus, the world hates you just like it hated Him. Now, this doesn’t mean that everyone who isn’t one of His followers as well hates you. You may (and should) have friends who are non-believers, some of whom may be very good friends. But, for anyone who is committed to the ends of the world (the elevation of self and the desires of the flesh above all else), they will hate the ends of the kingdom toward which you are working (the elevation of God and the humiliation of self), a hatred which will eventually be worked out through you.
Persecution should never surprise us as followers of Jesus. If we behave as He did, we will be treated as He was as well. This should be a mark of pride, knowing that we are on the right track.
